Preparation of thiochromans via thermal cyclization

Formation of the thiochroman ring system is achieved by a two step synthesis that involves heating 3-thiophenyl-1-propanols or 4-thiophenyl-2-butanols in toluene with catalytic amounts of p-toluenesulfonic acid. The propanols are made by the addition of s

Reduction of β-Arylthio- or β-Alkylthio-αβ-Unsaturated Ketones

The preparation and reduction of β-arylthio or β-alkylthio-αβ-unsaturated ketones (1) with lithium aluminium hydride or sodium borohydride have been examined.Reduction of the ketones (1) with lithium aluminium hydride gave αβ-unsaturated ketones (2), in which the olefinic (R1) and carbonyl (R2) substituents are reversed compared with the starting αβ-unsaturated ketone (1), or the saturated γ-hydroxy-sulphides (3).Reduction of the ketones (1) with sodium borohydride afforded only the αβ-unsaturated ketones (2).Reduction of (1) with sodium borohydride in the presence of metal halides gave the saturated ketones (5).
