The β-glycosyl esters of cis-cinnamic acid were synthesized directly using Hannesian’s unprotected glycosyl donor and the carboxylic acid in toluene. This protocol does not require protecting groups on the glycosyl donors, and high stereoselectivity was achieved. The first synthesis of a potent allelochemical, 1-O-cis-cinnamoyl-β-d-glucopyranose, is also described.
使用Hannesian未保护的糖基供体和甲苯中的羧酸,直接合成了顺式肉桂酸的β-糖基酯。该方案不需要糖基供体上的保护基,并且实现了高立体选择性。还描述了有效的化感化学物质1 - O-顺式-肉桂酰基-β-d-吡喃葡萄糖的首次合成。
