Grignard additions to 2-uloses: Synthesis of stereochemically pure tertiary alcohols

The addition of Grignard reagents to a number of 2-uloses has been investigated. Despite initial low diastereoselectivities it was found that tuning the ketone starting materials and studying solvent effects allowed formation of a single alcohol product.

n-Pentenyl glycosides in the efficient assembly of the blood group substance B tetrasaccharide

The fact that n-pentenyl glycosides (nPGs) are stable to a wide variety of reaction conditions but yet can be chemospecifically activated is advantageous for the efficient, convergent assembly of oligosaccharides. The nPGs are prepared directly from the a
