Abstract

A biomimetic total synthesis of scabellone B is described. Through sequential regioselective introduction of a geranyl group by means of silyl protection, oxidative dimerization, and biomimetic oxo-6π electrocyclization with good cyclization selectivity, a biomimetic ­approach to scabellone B was achieved in five steps and 32% overall yield.

Key words

total synthesis - protecting groups - dimerization - electrocyclic reactions - natural products
