Dual Photoredox/CpTi(IV)-Catalyzed Reductive Cyclization of Tertiary Bromide with Nitrile for Constructing 4a,9a-Heterocycle-Fused Tetrahydrocarbazole
{{output}}
In this study, dual photoredox/CpTi(IV) catalysis has been developed for the reductive cyclization of 3a-bromo-hexahydropyrroloindoline or 3-bromo-tetrahydrofuroindole with the appendage nitrile, providing rapid access to a series of 4a,9a-heterocycle-fused te... ...
