experimental part, p. 645 - 649 (2009/11/30)
(Chemical Equation Presented) An efficient, convenient, one-pot synthesis of 2,4(1H,3H)-quinazolinediones and 2-thioxoquinazolinones was accomplished in good yields via the novel reductive cyclization of ethyl 2-nitrobenzoates with isocyanates or isothioc
