Conditions are reported for the alkylation and acylation alpha to the sulphonate of a butyrolactone carrying a 5-phenylsulphonyl group. Yields are good if the alkyl or acyl halide is sufficiently reactive. The phenylsulphonyl group is initially retained and studies of its elimination are described. The corresponding system with nitrile in place of phenylsulphonyl appears to be a less satisfactory synthon
报道了带有5-苯基磺酰基的丁内酯的磺酸烷基化和α-酰化的条件。如果烷基或酰基卤具有足够的反应性,则收率良好。最初保留了苯磺酰基,并描述了其消除的研究。对于所需化学而言,用腈代替苯磺酰基的相应体系似乎不是令人满意的合成子。
