Daan J.A. Crommelin,Jon S. B. de Vliegerycles can be obtained by 1,3-dipolar cycloaddition reactions between an olefin and a nitrile oxide or a nitrone. This reaction generates one C–C and one C–O bond and up to three chiral centres in one step. In the present chapter, we aim to summarize and discuss reports of these cycloadditions on sug

David F. Driscoll,David F. Nicolid a hydroxyl or amine function allows access to promising heterocyclic compounds of particular interest resulting from reactions taking advantage of the electrophilic character of the cyano group and the nucleophilic character of hydroxyl and amino groups. Thus, α-hydroxynitriles (cyanohydrins) or α

Hermitian Systems and Non-Hermitian Systems,l phthalane .-glycosides, in which a phthalane ring and sugar unit form a spiroketal framework, have garnered enormous attention from wide research areas because such a fascinating spirocycle motif is found in antibiotic natural products, i.e., papulacandins and their relatives. Moreover, recent rep
