摘要：
The visible-light-mediated aerobic desulfurization and aromatization of Biginelli 3,4-dihydropyrimidine-2(1H)-thiones for a onestep synthesis of 2-unsubstituted pyrimidines was established. The protocol uses molecular oxygen as an inexpensive oxidant, with visible-light irradiation, and eosin B as an organophotoredox catalyst.
