30.4 Product Class 4: S,N-Acetals (α-Amino Sulfur Derivatives)

DOI: 10.1055/sos-SD-030-00450

General Introduction

Functional groups possessing an sp3-hybridized carbon bonded to both sulfur and nitrogen, for example the α-amino sulfur derivatives 1, are known as S,N-acetals. The SCN function may form part of a ring structure to generate a large number of heterocyclic systems 2, which are, for example, found in the sulfur-containing bicyclic β-lactams penam (3) and cepham (4) (Scheme 1).
