imidazoline ringexpansion (HIRE) methodology was extended to readily available tetracyclic [1,4]thiazepines as well as sulfoxide and sulfone analogs thereof. The reactions resulted in the facile formation of a rare medium-sized [1,4,7]thiazecine ringsystem that has an emerging utility in bioactive compound design. Comparing the HIRE rates for representative compounds in the three groups of substrates
A new approach to the synthesis of 10‐ and 11‐membered lactams via hydrated imidazoline ringexpansion is described. In addition to the ringexpansion an alternative course of the hydrated imidazoline evolution was discovered, for the first time, which gave N‐aminoethyl derivatives.
