Synthesis of cyclopropyl glycosides and their use as novel glycosyl donors

Efficient O- and S-glycosylation with ortho-2,2-dimethoxycarbonylcyclopropylbenzyl thioglycoside donors by catalytic strain-release

“…1B). 4 Donor-acceptor cyclopropanes (DACs) have been recognized as a special and valuable cyclopropane building block that can undergo facile nucleophilic ring-opening reactions of various C-, N-, O-, S-, and Se-nucleophiles facilitated by the liberation of the ring strain, rendering their chemistry one of the most important pillars in the modern synthesis of carbo-and heterocyclic compounds. 5 Chemical glycosylation assumes paramount importance in synthetic carbohydrate chemistry to acquire sufficient amounts of structurally well-dened and compositionally homogeneous materials for unveiling their key functions in numerous biological processes as well as their potential as the new generation of therapeutics.…”
