The aim of this review is to emphasize the value of unsaturated carbohydrate derivatives as a ground floor for useful synthetic transformations. In this context, we highlight the rich chemistry of Δ2,3 unsaturated pyranosides by way of the different transformations carried out in the Fraser-Reid laboratories during the past four decades. These transformations have all led to the synthesis of natural products. Cyclopropanated deri Read More

The recent developments on the synthetic applications of polyunsaturated silanes are reviewed. Different substrates will be considered, ranging from silylated conjugated dienes, enynes, polyenynes, diynes and polyynes. All these compounds represent versatile building blocks in the organic synthesis, as demonstred from the numerous applications, regarding especially the stereoselective synthesis of natural products with a Read More

This review focused on recent advances in free radical chemistry in water or aqueous media. Highlights in the progress have been made in the last decade to “tame” the reactive free radical species in aqueous phase reactions. Recent advances in several classes of widely useful free radical reactions in water have expanded the versatility and flexibility of the carbon-carbon bond formation. The review will also explore the rec Read More

This review describes the formation of five- and six-membered heterocyclic rings in various compounds by radical cyclisation and covers the recent literature mostly of 2007.

Daphniphyllum alkaloids are a growing group of secondary metabolites of great structural diversity, with complex polycyclic skeletons from Daphniphyllum plants. A large number of new Daphniphyllum alkaloids with novel frameworks have been isolated from Daphniphyllum species in the past decade. These unusual structural characteristics will attract the attention of scientists in the fields of organic synthesis, bioactivi Read More
