Abstract: The combination of visible-light and tris(trimethylsilyl)silane promoting intramolecular reductive cyclization protocol for the synthesis of functionalized indolines and 2,3-dihydrobenzofurans has been developed. The transformations occur in the absence of transition metal and additional photocatalyst. In… read more here.

Abstract: A visible light-driven carbon–carbon bond-forming cyclization cascades under metal- and catalyst-free conditions have been reported. The cascade is initiated through a transient alkyl radical intermediate that is formed by direct... read more here.
