摘要

A mild and efficient method to synthesize dibenzo[b,f]thiepin-10-one derivatives was achieved,with key steps of PPE mediated cyclization of seven-member ring and selective ketone a bromination with CuBr2.Reaction of a alkylation and arylation of ketones were also optimized to finish the synthesis with good overall yield.
