Reaction of the tosyl imides 6 and 8 of 1,3-dithiane and 1,3,5-trithiane with sodium hydride and alkyl iodides in DMF yields anti alkylated products in all cases. In the case of the trithiane imide 8, both mono-and di-alkylation is observed. Preparation of cyclic sulfimide analogues of Eliel's oxathiane is shown to be problematic, but a new class of O,S-acetals, namely 4-bromophenylthiomethyl (BPTM)
在所有情况下,在DMF中1,3-二硫醚和1,3,5-三硫胺的甲苯磺酰基酰亚胺6和8与氢化钠和烷基碘的反应都会产生抗烷基化的产物。在三噻吩酰亚胺8的情况下,观察到单烷基化和二烷基化。Eliel oxathiane的环状硫酰亚胺类似物的制备显示有问题,但是引入了新的O,S-乙缩醛,即4-溴苯硫基甲基(BPTM)醚来替代其麻烦的苯基硫代甲基(PTM)类似物。
