A set of enantiopurecarbohydratemimetics has been synthesized via Lewisacid promoted cyclization of 1,3-dioxolanyl-substituted enol ethers as a crucial new step providing highly functionalized 3,6-dihydro-2H-pyran derivatives. The flexible approach starting from glyceraldehyde-derived nitrone is comprised of only six simple steps smoothly allowing synthetic modifications at the different stages
