Abstract

Synthesis of Tetrahydropyrazolo[1,5-c]pyrimidine-2,7(1H,3H)-diones. -A straightforward synthesis of the title compounds (VII) and (XII) is presented. The strategy involves preparation of selectively functionalized pyrrazolidinones and final cyclization with CDI. -(GROSELJ*, U.; PODLOGAR, A.; NOVAK, A.; DAHMANN, G.; GOLOBIC, A.; STANOVNIK, B.; SVETE, J.; Synthesis 45 (2013) 5, 639-650, http://dx.doi.org/10.1055/s-0032-1318107 ; Fac.
