using lithium bis(trimethylsilyl)amide afforded the (+)-melithiazol B (1), whose spectral data were identical with those of the natural (+)-1 from the myxobacterium Archangium gephyra, strain Ar 7747. Moreover, the selective olefin formation between (+)-(4R,5R)-5 and the bithiazole-type sulfone [(′)-7] followed by transformation gave the (+)-melithiazol M (2), whose spectral data were identical with those
报道的 (+)-手性醛 [(4R,5R)-5] 与衍生自联噻唑型碘化鏻 (6) 的磷酰苯胺之间的 Wittig 反应,使用双(三甲基甲硅烷基)氨基锂得到 (+)-甲基噻唑 B (1),其光谱数据与来自粘细菌 Archangium gephyra 菌株 Ar 7747 的天然 (+)-1 的光谱数据相同。此外,(+)-(4R,5R)-5 和联噻唑之间的选择性烯烃形成- 型砜 [(')-7] 然后转化得到 (+)-甲基噻唑 M (2),其光谱数据与来自粘杆菌 Archangium gephyra 菌株 Ar 7747 的天然 (+)-2 的光谱数据相同。
