摘要：

The use of trifluoroacetic acid-boron trifluoride combination is highly effective in dichloromethane for the activation of 1-phenylethylimine of methyl or ethyl glyoxylates as heterodienophiles in Diels-Alder cycloaddition reactions with a series of conjugated dienes. High regio-(meta:para) and stereo-(endo:exo) selectivities are observed at low temperature. Asymmetric induction is very high (>98%) with cyclopentadiene but remains low in the other cases.
