This communication presents studies that illustrated nitroso Diels-Alder adduct has been obtained in uniformly high enantioselectivity via a tandem nitro so aldol/Michael reaction using an amine catalyst.Abstract:
This communication presents studies that illustrated nitroso Diels−Alder adduct has been obtained in uniformly high enantioselectivity via a tandem nitroso aldol/Michael reaction using an amine catalyst. The regiochemical outcome of this construction is documented to be the opposite to that of the normal nitroso aldol reaction, which has been determined by X-ray analysis. The reaction of the enone with silver−BINAP catalyst has also been investigated in conjunction with the control of regiochemistry in a stepwise process.read more

Lewis Base Catalysis in Organic Synthesis
TL;DR: It has become increasingly apparent that the behavior of Lewis bases as agents for promoting chemical reactions is not merely as an electronic complement of the cognate Lewis acids: in fact Lewis bases are capable of enhancing both the electrophilic and nucleophilic character of molecules to which they are bound.
