Abstract

Whereas 3-diacylaminoquinazolin-4(3H)-ones (DAQs) have been previously shown to undergo rapid exo/endo-endo/exo conformational interconversion of their imide carbonyl groups, the title DAQs are believed to exist in one single exo/endo form and consequently their N-N bonds are chiral axis: one of these DAQs, substituted with a diphenylmethyl group on the Q-2 position, reacts preferentially with one enantiomer of racemic 2-methyl-piperidine at the2-acetoxypropanoyl imide carbonyl group (ee 94%).
