The stereochemistry of the cycloaddition of nitroethylene, as a model of 6-nitrobenzofuroxans, with ethenol and vinylamine has been studied at the ab initio DFT level. MO analysis reveals that these inverse electron demand Diels−Alder reactions are

A Theoretical Investigation of Enantioselectivity:Michael Reaction of Secondary Enamines with Enones
Publikováno v:
Helvetica Chimica Acta. 73:552-573
A theoretical study of the enantioselective Michael-type addition of chiral secondary enamines to enones has been achieved. In a first step, the structures of various free enamines have been investigated at the ab initio and MNDO levels. The results

A theoretical study (SCF PS-HONDO + CI) of the stability of the tribromide anion Br3− has been carried out. On the basis of qualitative MO arguments and MNDO calculations, we propose a first approach to the mechanism of electrophilic aromatic subst
