Rapid Access to\nTriarylmethanes (TRAMs) Enabled by\nDirect Electrolysis of Indolizines with Carbonyls

A fast, scalable, transition metal-free,\nelectrochemical sp<sup>2</sup> geminal functionalization of carbonyls\nenabled by anodic\noxidation of non-prefunctionalized chromone-fused indolizines to access\nthe triarylmethanes (TRAMs) is disclosed for the first time. This\nmomentary electrochemical approach features the use of readily available\ncarbonyls, implantation of the C(sp<sup>3</sup>) center (well-known\nfor dramatically improving biological active potency), a broad substrate\nscope, and excellent yields of TRAMs with fluorescence properties.
