Ring-opening of chiral N-(3,4-dihydro-4-oxoquinazolin-3-yl)-substituted aziridines (Q*-substituted aziridines): Access to Q*-free chirons

Atkinson, Robert S.,Ayscough, Andrew P.,Gattrell, William T.,Raynham, Tony M.

, p. 497 - 500 (1998)

The presence of the quinazolin-4(3H)-one ring (Q*) in N-(Q*)-aziridines facilitates ring-opening by nucleophiles: removal of the Q* group from enantiopure ring-opened products gives useful chirons.
