Multi-amino groups and nitrogen donors compound was discovered as an organocatalyst for N-alkylation of alcohols with amines in the presence of Mo(CO)6. The Mo(CO)6/organocatalyst binary system has shown to be a highly active catalyst for the N-alkylation reaction between alcohols and amines with excellent tolerance of variable starting materials bearing different functional groups. Of particular note, this method possessing a superiority selectivity in the synthesis of N-alkylated amines or imines, which can be controlled by the reaction temperature. The cooperative catalysis mechanism in combination of Mo(CO)6 with organocatalyst was elucidated by control experiments.

We report N,N-dimethylformamide-stabilised Pd nanoparticle (Pd NP)-catalysed transfer vinylation of alcohols from vinyl ether. Pd NPs combined with bathophenanthroline exhibited high catalytic activity. This reaction proceeded with low catalyst loading and the catalyst remained effective even after many rounds of recycling. The observation of the catalyst using transmission electron microscopy and dynamic light scattering implied no deleterious aggregation of Pd NPs.

Hexafluoroisopropanol (HFIP)-catalyzed direct dehydroxydifluoro-alkylation of benzylic and allylic alcohols with difluoroenoxysilanes is developed. This procedure enables the synthesis of a broad range of alpha,alpha-difluoroketones, a class of highly valuable intermediates and building blocks in medicinal and organic chemistry. Here, we have demonstrated for the first time that HFIP could act as a powerful catalyst for fluorinated carbon-carbon bond formation. The application of this protocol in late-stage dehydroxydifluoroalkylation of potentially bioactive drugs and natural products has also been carried out.

Borrowing hydrogen from alcohols, storing it on a catalyst and subsequent transfer of the hydrogen from the catalyst to an in situ generated imine is the hallmark of a transition metal mediated catalytic N-alkylation of amines. However, such a borrowing hydrogen mechanism with a transition metal free catalytic system which stores hydrogen molecules in the catalyst backbone is yet to be established. Herein, we demonstrate that a phenalenyl ligand can imitate the role of transition metals in storing and transferring hydrogen molecules leading to borrowing hydrogen mediated alkylation of anilines by alcohols including a wide range of substrate scope. A close inspection of the mechanistic pathway by characterizing several intermediates through various spectroscopic techniques, deuterium labelling experiments, and DFT study concluded that the phenalenyl radical based backbone sequentially adds H+, H and an electron through a dearomatization process which are subsequently used as reducing equivalents to the C-N double bond in a catalytic fashion.

Citric acid-modified graphite-like carbon nitride materials (GCN-zCA) were synthetized by thermal copolymerization of dicyandiamide with different amounts of citric acid (z = between 5 and 25 mg). The resulting materials presented surface porosity, defective polymeric structure, and enhanced visible light absorption in the 450-700 nm range, attributed to the existence of mid-gap states and n-pi* electronic transitions. All the modified catalysts presented high selectivity (>99 %) towards the conversion of p-anisyl alcohol into p-anisaldehyde under visible-LED irradiation, the best performing photocatalyst (GCN-20CA) reaching 63 % yield (contrasting with 22 % obtained with bulk GCN) after 240 min reaction. GCN-20CA was also applied for hydrogen generation from water splitting. The modified material practically duplicated the hydrogen production when compared to bulk GCN (75 and 44 mu mol H-2 evolved in three hours, respectively), by using platinum nanoparticles as co-catalyst and EDTA as sacrificial electron donor. Moreover, p-anisyl alcohol was successfully used as sacrificial agent for water splitting, with simultaneous production of p-anisaldehyde and H-2. Reusability tests showed that GCN-20CA remained stable in a series of consecutive runs both for p-anisaldehyde synthesis and hydrogen production.

The ring-opening of epoxides is a synthetically significant process widely applied in all kinds of chemistry. Herein, we report the catalytic and highly enantioselective variant of this reaction exploiting our recent endeavors to design and synthesize chiral bipyridine type ligands. A Sc-complex with a newly developed bipyridine ligand exhibited high reactivity and stereocontrol in the desymmetrization of meso-epoxides with various alcohols. The respective enantiomerically enriched 1,2-alkoxyalcohols were obtained with e.r. values of up to 99.5:0.5 for various alcohols regardless of their nature (benzyl, alkyl, cycloalkyl, allyl, propargyl, etc.). We attempted ring-opening of meso-epoxides with anilines as well; however, it proceeded with lower enantioselectivity and was strongly depended on the electronic effect of substituents attached to the aromatic ring.

A green method for the oxidation of alcohols to carboxylic acids was developed using a novel co-catalytic system based on gold, silver, and copper catalysts. This reaction system was conducted under atmospheric oxygen in water and mild conditions to selectively oxidize 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid, as a building block for polyethylene furanoate, which is a 100% bio-based, future alternative to the petroleum-based polyethylene terephthalate. Furthermore, various primary alcohols were conveniently oxidized to their corresponding carboxylic acids in up to quantitative yields.

Purpose: As a third-generation EGFR TKI has been taken orally, Osimertinib effectively inhibits mutant EGFR, including T790M EGFR resistance mutations. Here, we examined real-world efficacy and tolerability of Osimertinib among Chinese patients with advanced EGFR T790M-mutant NSCLC. Patients and Methods: A total of 106 advanced NSCLC patients who were taking Osimertinib following disease progression after EGFR-TKIs or other treatments were retro-spectively recruited in this study. The PFS and OS after Osimertinib treatment were analyzed as the primary endpoints. Results: Osimertinib was used as a second line and >= 3rd line treatment in 22.6% and 77.4% of the patients, respectively. DCR and ORR were 93.4% and 57.5%, respectively. Median PFS was 12.4 12 (95% CI, 10.5-13.5) months. The PFS was 11 (8.0, 14.0) and 12 (10.3,13.7) months (p = 0.373), in patients with and without CNS metastasis, respectively. PFS in 2nd and >= 3rd line treatment was 11 (9.0, 13.0) and 12.4 12 (8.9, 15.1) months (p = 0.799), respectively. In patients with EGFR exon 19 deletion and exon 21 L858 mutation, the median PFS was 11 (9.2, 12.8) and 12 (9.2, 14.8) months, respectively (p = 0.833). Median PFS in the monotherapy group and combined anti-angiogenesis group was 11 (9.9,12.1) and 14 (11.2,16.8) months, respectively. Median OS after Osimertinib initiation was 27 (19.6, 34.4) months: 15 (6.9, 23.1) and 27 (22, 32) months in patients with and without CNS metastasis (p=0.027), 27 (20.3,33.7) months and (undefined) as second line or >= 3rd line of treatment (p = 0.421), respectively. In patients with exon 19 deletion, the median OS was not reached, and in patients with exon 21 L858 mutations, the median OS was 23 (19.1,29.9) months (p=0.027). Median OS in the monotherapy group was 27 (21.7,32.3) months, and in combined anti-angiogenesis group was not reached (p=0.68). Conclusion: Osimertinib can effectively treat advanced NSCLC with T790M mutations independently of previous treatment lines.
