摘要

A practical and novel organocatalytic chemo-and enantioselective process for the cascade synthesis of highly substituted 2-alkyl-cyclohexane-1, 3-diones and Wieland-Miescher (WM) ketone analogs is presented via reductive alkylation as a key step. First time, we developed the one-step alkylation of dimedone and 1, 3-cyclohexanedione with aldehydes and Hantzsch ester through an organocatalytic reductive alkylation strategy. Direct ...
