The AuI-catalyzed reaction of 2-(1-alkynyl)-2-alken-1-ones with azomethine imines regio- and diastereoselectively affords furo[3,4-d]tetrahydropyridazines in a tandem cyclization/intermolecular [3+3]-cycloaddition process under mild conditions.

The more dipoles, the merrier: An asymmetric [3+3] cycloaddition of azomethine ylides derived from imines 1 with azomethine imines 2 in the presence of a chiral ferrocenylphosphine-copper catalyst afforded highly functionalized heterocyclic products 3 in high yield with excellent enantio- and diastereoselectivity (see scheme; DBU=1,8-diazabicyclo[5.4.0]undec-7-ene). The 1,3-dipolar reaction partners can be readily prepared from aldehydes. Copyright
