Hetero Diels–Alder reactions in carbohydrate chemistry: a new strategy for multichiral arrays synthesis
Abstract
Hetero Diels–Alder reactions of α,β-unsaturated ketones (5) and (6) derived from carbohydrates with enol ethers (7) led to the formation of fused dihydropyrans with complete stereospecificity and creation of chiral centres on the newly formed template.
