Abstract

Abstract β-Sulfenyl α, β-unsaturated ketones 1a-c reacted with guanidine or amidines to give pyrimidine derivatives 3 in 14-76% yields. Treatment of ketones 1 with diamines such as ethylenediamine and o-phenylenediamine afforded the seven-membered heterocycles, 2, 3- dihydro-1, 4-diazepine 5 and 2, 3-benzo-1, 4-diazepines 8a-c.
