Thermal and acid-catalysed sigmatropic rearrangements of 4-(N-methyl-N-allylamino)-5-methoxy-1,2-benzoquinones 3 and of 4-(2-vinyl-aziridino or azetidino)-5-methoxy-1,2-benzoquinones 7 were studied and compared. The mechanisms of these reactions are discussed.

A simple and efficient method is described for a general synthesis of 4-dialkylamino-5-methoxy-1,2-benzoquinones 3 which involves, in polar solvents, a regioselective (>95%) nucleophilic monosubstitution by a wide range of secondary aliphatic amines on an easily prepared 1,2-quinone 1. Regioselectivity is not observed in the reaction of primary amines with 1, but a further reaction with an alcohol in basic medium allows valorization of the undesirable product.
A Stereoselective Approach to the Synthesis of Allylic and Homoallylic Amines

Nitrones undergo dipolar cycloaddition with vinyl- and allylsilane derivatives to produce substituted isoxazolidines which are versatile intermediates for the preparation of allylic and homoallylic amines.During olefination, the alkene geometry ca
