摘要：

[4+2] Cycloaddition reactions of alpha,beta-unsaturated carbonyl compounds to 4,4-bis(trifluoromethyl)-1-hetero-3-azabuta-1,3-dienes occur exclusively across the carbon-oxygen double bond. A complete change of site selectivity is observed in the presence of equimolar amounts of 4-dimethylaminopyridine (DMAP).
