Article abstract of DOI:10.1016/0040-4039(96)00046-9

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.
