Salacinol (4) is one of the active principles in the aqueous extracts of Salacia reticulata that are traditionally used in Sri Lanka and India for the treatment of diabetes. The syntheses of salacinol (4), the enantiomer of salacinol (5), and a diastereomer (7) are described. The synthetic strategy relies on the selective nucleophilic attack of 2,3,5-tri-O-benzyl-1,4-anhydro-4-thio-D- or L-arabinitol
Salacinol(4)是Salacia reticulata水提取物中的活性成分之一,传统上在斯里兰卡和印度用于治疗糖尿病。描述了水杨醇(4),水杨醇的对映体(5)和非对映体(7)的合成。合成策略依赖于2,3,5-三-O-苄基-1,4-脱水-4-硫代-D-或L-阿拉伯糖醇在C-1的2,4-O-亚苄基上的选择性亲核攻击D-或L-赤藓糖醇-1,3-环硫酸盐。这项工作旨在解决关于柳氮醇的确切结构的歧义,并最终确定天然产物的结构。
