A short syntheticapproach with broad scope to access five- to seven-membered cyclic sulfoximines in only two to three steps from readily available thiophenols is reported. Thus, simple building blocks were converted to complex molecular structures by a sequence of S-alkylation and one-pot sulfoximine formation, followed by intramolecular cyclization. Seventeen structurally diverse cyclic sulfoximines
The invention provides new compounds of the formula: Ar--SO.sub.Y --Alk--NR.sub.1 R.sub.2 in which Ar represents a phenyl group, a phenyl group substituted by one or more C.sub.1 -C.sub.4 alkyl, CF.sub.3 and COOH groups, or a 2-benzimidazolyl group optionally substituted in the 1-position, Y is 0 or 1, Alk is a C.sub.2 -C.sub.5 hydrocarbon radical with a straight or branched chain, and NR.sub.1 R.sub.2 is a secondary, tertiary or N-heterocyclic amino group, and their addition salts which show pharmacological activity, e.g. as analgesics, anti-inflammatory agents, and anorexigenic agents.
