Asymmetric organocatalytic vinylogous Michael addition triggered triple-cascade reactions of 2-hydroxycinnamaldehydes and vinylogous nucleophiles: construction of benzofused oxabicyclo[3.3.1]nonane scaffolds
An organocatalytic vinylogous Michael addition triggered triple-cascade reaction has been developed. 2-Hydroxycinnamaldehydes worked under iminium activation with either acyclic or cyclic ketone-derived α,α-dicyanoalkenes, yielding the benzofused oxabicyclo[3.3.1]nonanes bearing one quaternary stereocenter with excellent stereoselectivities.

Basic ionic liquid as catalyst for the efficient and green synthesis of 2-amino-3-nitrobenzonitriles in ethanol
A basic ionic liquid, [BmIm]OH was used as catalyst in the cyclocondensation of various kinds of vinylmalononitriles with nitroolefins in ethanol at reflux. A series of 2-amino-3-nitrobenzonitriles were obtained in reasonable yields. The straightforward and green protocol was found to be fairly efficient, and the catalyst could be recycled and reused in subsequent reactions with consistent activity. The mechanism of the reaction was discussed.

Iminoformylation Reaction of Substituted Crotonnitriles. I. Synthesis of New N,N-Disubstituted 4-Amino-1,1-dicyanobuta-1,3-dienes
A usefull and efficient method for the synthesis of 4-amino-1,1-dicyanobuta-1,3-dienes 10-20 based on the iminoformylation reaction of crotonnitriles 7-9 with the system triethyl orthoformate/secondary amine in the presence of an acidic catalyst is described.This novel route to the title compounds yields products which are easy to isolate and to purify and also allows to prepare the hitherto unknown N-aryl substituted 4-amino-1,1-dicyanobuta-1,3-dienes.Hence it is advantageous as compared to existing iminoformylation reactions of crotonnitriles using formamide acetals.
