A general approach to the synthesis of iridoid aglycones is reported. A combination Claisen rearrangement/nitrile oxide cycloaddition sequence has permitted the facile annulation of a highly functionalized cyclopentane ring onto a simple glycal derived from D-xylal. The title aglycones have been prepared and the work has culminated with a stereoselective totalsynthesis of (-)-specionin. Two other

The iridoidspecionin is an effective antifeedant against the Eastern spruce budworm. Previous synthetic work has shown that the proposed structure was incorrect. Presently the total synthesis of the revisedstructure is described. The structure elucidation, with special emphasis on the anomeric C-3 configuration, is based on chemical evidence and 1H NMR analysis.
虹膜类胶体蛋白是针对东方云杉芽虫的有效拒食剂。先前的综合工作表明,拟议的结构是不正确的。目前,描述了修订结构的总合成。结构阐明是基于化学证据和1 H NMR分析,其中特别侧重于端基C-3构型。
