Reduction of 5-hydroxy-3,3,6,6-tetramethylthiepan-4-one, now readily available by an improved synthesis, with chelating and non-chelating reducing agents allows the preparation of the two diastereoisomers of the title compounds whose structures and conformations are determined by X-ray crystal structure analysis.
现在可以通过螯合和非螯合还原剂通过改进的合成方法轻松还原5-羟基-3,3,6,6-四甲基噻吩-4-酮,可以制备标题化合物的两种非对映异构体,其结构和结构通过X射线晶体结构分析确定构象。
