摘要：

Attempted Pauson-Khand cyclisation of exo- methylene carbohydrate enynic substrates is described. 3-Exo methylene derivative cyclises to give a normal Pauson-Khand product while cyclisation of a 4-exo methylene analog follows a previously unreported pathway to give fused ''[4.1.0] bicycloheptene pyranose'' tricyclic product.
