Organocatalytic enantioselective direct alkylation of phloroglucinol derivatives: asymmetric total synthesis of (+)-aflatoxin B2

Abstract

The organocatalytic enantioselective Friedel–Crafts alkylation of phloroglucinol derivatives with enals is reported, providing general access to the benzylic chiral centers shown in a variety of phloroglucinol natural products. The synthetic utility is demonstrated by the very concise asymmetric total synthesis of aflatoxins B2.
