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
研究了用氢化铝锂或硼氢化钠制备和还原β-芳硫基或β-烷硫基-αβ-不饱和酮(1)。用氢化铝锂还原酮(1)得到αβ-不饱和酮(2),其中烯烃(R 1)和羰基(R 2)取代基与起始的αβ-不饱和酮(1)相比是相反的,或者饱和的γ-羟基硫化物(3)。用硼氢化钠还原酮(1)仅得到αβ-不饱和酮(2)。在金属卤化物存在下用硼氢化钠还原(1),得到饱和酮(5)。
