Abstract
Benzothiazepinones and benzoxazepinones were converted into thioamides and then into cyclic thioimidates, which were annelated to give β-lactams by treatment with an acid chloride and a weak base. Reactions of these homologues of cepham and penam with periodate led to rearrangement to 1,4-thiazonine and 1,4-oxazonine derivatives.This publication has 1 reference indexed in Scilit:
