Benzoic acidDirect reduction of seven benzoic acids to alcohols via sodium borohydride–bromine (NaBH 4 –Br 2 ) reagent was developed. The isolated yields for the seven acids to reduce reached 60.6–90.1%. This new synthesis route has the advantages of simple of application, low cost, mild ...
NaBH4 favored the creation of diol 213 with hydride (H−) transfer to the Si face of the ketone. Deprotection via cleavage of the benzyl-ester of 213 was achieved by a hydrogen gas atmosphere and Pd/C, producing maslinic acid 214 (Scheme 5.25) (Nelson et al., 2015). Sign in...
More importantly, this novel synthesis strategy significantly increased the interaction between Rh nanoparticles and N-doped carbon in contrast with the conventional impregnation and NaBH4 reduction methods, thus preventing the Rh nanoparticles from migration, aggregation, and leaching from the support ...
