摘要：

New highly substituted 3,4-dihydro-2H-pyrans were synthesized with high ENDO selectivity by high pressure hetero Diels Alder reactions of alpha,beta-unsaturated aldehydes and enol ethers in the presence of lanthanide-catalysts. Chiral induction was studied using chiral catalysts, a chiral enol ether and a combination of these chiralities.
