The direct condensation of saturated or un-saturated aldehydes with methyl phenylsulphinylacetate can be effected with the products undergoing base catalysed rearrangements those from saturated aldehydes yielding γ-hydroxy-αβ-unsaturated esters, whilst croton-aldehyde gives rise to methyl 6-phenylsulphinylhexa-2,4-dienoate.
饱和或不饱和醛与苯基亚磺酰基
乙酸甲酯直接缩合可以通过由饱和醛进行碱催化重排的产物产生,生成γ-羟基-αβ-不饱和酯,而
巴豆醛则生成甲基6-苯基亚磺酰基己基-2。 ,4-二羟
戊酸酯。
