Generation of nitrile ylides, 4 and 22, via the base-catalysed 1,3-dehydrochlorination of imidoyl chlorides, 3 and 21, gives the imidazoles, 13, 23 and 24. These imidazoles are formed by the cycloaddition of the nitrile ylides, 4 and 22, to their pre

a,b;g,d-Unsaturated nitrile oxides 6, 13 have been prepared from the corresponding aldehydes via sequential oxime formation, chlorination, and dehydrochlorination. These nitrile oxides show unexpected stability, presumably due to delocalisation, and

A novel synthesis of didehydroamino acid (DDAA) esters 4 is described, starting from aldimines 1 . The mechanism for this reaction involves the cycloaddition of an azomethine ylide 2 to an imine 1 , followed by the base-catalysed ring-opening of the
