One-pot synthesis of 2,3-dihydro-2-thioxoquinazolin-4(1H)-ones from nitro-compounds with the aid of tin(II) chloride

(Chemical Equation Presented) A facile synthetic method using SnCl 2·2H2O system to promote the novel reductive cyclization of 2-nitrobenzamides and isothiocyanates is described. Sequentially, a series of 2,3-dihydro-2-thioxoquinazolin-4(1H)-ones were synthesized in good yields.

One-pot synthesis of quinazoline-2,4(1H,3H)-diones and 2- thioxoquinazolinones with the aid of low-valent titanium reagent

(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
