Abstract
Diastereoselective 1,3-dipolar cycloadditions between C-methoxycarbonyl-N- arylnitrilimines 2 and the C=N bond of enantiopure N-(1-phenylethyl)-1- arylmethanimines 3 gave diastereoisomeric 5-aryl-4,5-dihydro-1,2,4-triazolines 4 and 5. A computational description of the E→Z isomerisation of the C=N bond of unsubstituted 3a is given.
