  Stereocontrolled synthesis of novel phytosphingosine-type glucosaminocerebrosides

  摘要：

  D-ribo-Phytosphingosine 1 was conveniently synthesized from N-benzoyl-D-glucosamine 3 by an improved route in which regioselective O-methanesulfonation and diastereoselective Grignard addition are involved as key steps. Using a synthetic intermediate of 1, novel D-ribo-phytosphingosinetype glycolipids 2a and 2b, unnatural homologues of antifungal cerebrosides Halicylindrosides, were efficiently synthesized in a stereocontrolled manner.

  Sphinga-4,8-dienine derivatives were synthesized from a vinyl-epoxide 5 via three routes. First, reaction of 5 with 2-dodecenyl cyanocuprate afforded a 1:1 mixture of (4E,8E)- and (4E,8Z)-sphingadienine derivatives in high yield. Second, the (4E,8E)-isomer was selectively synthesized via allylic bromide-allylic sulfone coupling followed by desulfonylation. Third, the (4E,8Z)-isomer was selectively

  Sphinga-4,8-​​二烯胺衍生物是通过三种途径由乙烯基环氧化合物5合成的。首先，5与2-十二碳烯基氰基癸酸酯的反应以高收率提供了（4 E，8 E）-和（4 E，8 Z）-鞘氨二烯衍生物的1：1混合物。其次，通过烯丙基溴-烯丙基砜偶联，然后进行脱磺酰化，选择性地合成了（4 E，8 E）-异构体。第三，通过S N选择性合成（4 E，8 Z）-异构体二（氰基甲基）铜-锂的2′-型添加，然后Wittig烯烃化。这些合成的中间体被转化为具有钙离子电活性的鞘氨二烯型葡糖脑苷脂1a和1b。
