Pan, Liangkun;Ke, Zhihai;Yeung, Ying-Yeung published 《Lewis Base Catalyzed Dioxygenation of Olefins with Hypervalent Iodine Reagents》. The research results were published in《Organic Letters》 in 2021.Category: alcohols-buliding-blocks The article conveys some information:
1,2-Diols were extremely useful building blocks in organic synthesis. Hypervalent iodine reagents were useful for the vicinal dihydroxylation of olefins to gave 1,2-diols under metal-free conditions, but strongly acidic promoters were often required. Herein, synthesis of 1,2-diols R1CHOHCHOHR2 [R1 = n-hexyl, Ph, Bn, etc.; R2 = H, Ph] and acetals R3CH2CH(OMe)2 [R3 = Ph, 4-MeOC6H4, (4-acetoxyphenyl), etc.] via catalytic vicinal dioxygenation of olefins with hypervalent iodine reagents using Lewis bases as catalysts was reported. The conditions were mild and compatible with various functional groups. To complete the study, the researchers used rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .
Desymmetrization of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas:579-43-1 Category: alcohols-buliding-blocks) using chiral phosphine catalyst has been reported. Conversion of meso-hydrobenzoin to trans-stillbene oxide by treatment with an aryl sulfonyl chloride and aqueous sodium hydroxide has been reported.
