Abstract
Abstract The reaction of N -unsubstituted imines of 2-hydroxyacetophenones with trichloro(trifluoro)ethylidene nitromethanes in the presence of DABCO proceeds via tandem oxa-Michael/aza-Henry additions (in dichloromethane) or aza-Michael addition (in benzene) to give 4-methyl-3-nitro-2-trichloro(trifluoro)methyl-2 H -chromenes or 1,1,1-trichloro(trifluoro)-3-nitro- N -[1-(2-hydroxyaryl)ethylidene]propan-2-amines, respectively.
