Nallagonda, Rajender; Karimov, Rashad R. published an article in 2021. The article was titled 《Copper-Catalyzed Regio- and Diastereoselective Additions of Boron-Stabilized Carbanions to Heteroarenium Salts: Synthesis of Azaheterocycles Containing Contiguous Stereocenters》, and you may find the article in ACS Catalysis.Category: alcohols-buliding-blocks The information in the text is summarized as follows:
Nucleophilic addition of diborylalkyl reagents to N-alkyl or N-acylpyridinium and related heteroarenium salts has been developed as a key step for the synthesis of nonaromatic nitrogen heterocycles that contain contiguous stereogenic centers. Derivatization of the dihydropyridine products for the synthesis of tetrahydropyridines and piperidines have also been described. After reading the article, we found that the author used Bis[(pinacolato)boryl]methane(cas: 78782-17-9Category: alcohols-buliding-blocks)
Bis[(pinacolato)boryl]methane(cas: 78782-17-9) belongs to organoboron compounds.Category: alcohols-buliding-blocks Organoboron compounds are versatile intermediates and as such are some of the most important classes of reagents in modern organic chemistry. This stems from their ease of preparation combined with their ability to undergo a broad range of chemical transformations.
