Synthesis of pyrrolo[3,2- d]pyrimidine-2,4(3 H)-diones by domino C-N coupling/hydroamination reactions
{{output}}
A variety of pyrrolo[3,2-d]pyrimidine-2,4(3H)-diones were prepared by a combination of Sonogashira reaction and subsequent cyclization by domino C-N coupling/hydroamination reaction. The optical properties (UV-vis absorption and fluorescence) depend on the sub... ...
