A General Regioselective Synthesis of Alcohols by Cobalt-Catalyzed Hydrogenation of Epoxides

A straightforward methodology for the synthesis of anti-Markovnikov-type alcohols is presented. By using a specific cobalt triphos complex in the presence of Zn(OTf)2 as an additive, the hydrogenation of epoxides proceeds with high yields and selectivities. The described protocol shows a broad substrate scope, including multi-substituted internal and terminal epoxides, as well as a good functional-group tolerance. Various natural-product derivatives, including steroids, terpenoids, and sesquiterpenoids, gave access to the corresponding alcohols in moderate-to-excellent yields.

Visible-Light-Mediated Anti-Markovnikov Hydration of Olefins

Considering that stoichiometric borane and oxidant are required in the classical alkene anti-Markovnikov hydration process, it remains appealing to achieve the transformation in a catalytic protocol. Herein, a visible-light-mediated anti-Markovnikov addition of water to alkenes by using an organic photoredox catalyst in conjunction with a redox-active hydrogen atom donor was developed, which avoided the need for a transition-metal catalyst, stoichiometric borane, as well as oxidant. Both terminal and internal olefins are readily accommodated in this transformation to obtain corresponding primary and secondary alcohols in good yields with single regioselectivity. This procedure can be scaled up to gram scale with a 230 turnover number based on photocatalyst.

Stereoselective production of (S)-1-aralkyl- and 1-arylethanols by freshly harvested and lyophilized yeast cells

Substituted (S)-1-phenyl- 2a-h and (S)-1-benzyl-propan-2-ols 4a and b, and (S)-1-phenylethanol 6 were produced from prochiral ketones 1a-h, 3a,b and 5 by reductions with freshly harvested Zygosaccharomyces rouxii and Debaryomyces hansenii cells. The bioreductions were also performed by lyophilized cells. Comparison of the secondary alcohols from the bioreductions 2b-e,g,h and 4a and authentic (S)-alcohols (S)-2b-e,g,h and (S)-4a synthesized from enantiopure (S)-methyloxirane 7 proved the absolute configuration of the products.
