Irradiation of 5-ethoxy-2,3-dihydro-2,2,6-trimethyl-1,4-thiazepine (1) leads to dimerization in aprotic media and solvent addition in methanol, with ring contraction via participation of sulphur; under the same conditions, the hydrochloride of (1) adds methanol without rearrangement.
辐射5-乙氧基-2,3-二氢-2,2,6-三甲基-1,4-噻氮平(1)导致质子惰性介质中的二聚反应和甲醇中溶剂的添加,并通过硫的参与使环收缩;在相同条件下,(1)的盐酸盐加入甲醇而没有重排。
