The chiral N , N′ -dioxide–Yb(OTf) 3 complex-catalyzed enantioselective aza-Diels–Alder reaction of Brassard’s diene with aldimines has been developed, giving the corresponding α,β-unsaturated δ-lactam derivatives in moderate yields with g

An efficient catalytic asymmetric hetero-Diels-Alder reaction of Brassard's diene with aliphatic aldehydes was reported. The catalyst, which was generated from (R)-BINOL, Ti(i-PrO)4, and 4-picolyl chloride hydrochloride, promoted the reaction smoothl

Schiff's bases 3 derived from tryptamine react with Brassard's diene 4 in the presence of EtAlCl2 to give functionalized 1,2,5,6-tetrahydropyridines which are subsequently transformed to indolo[2,3-a]quinolizines 8–10 by the Bischler-Napieralski re

The catalyst generated promotes the asymmetric reaction of the diene (I) with aromatic and conjugated aldehydes to give functionalized esters of type (III) with excellent enantioselectivity.
