Exploratory, mechanistic, and synthetic aspects of silylarene-iminium salt SET photochemistry. Studies of diradical cyclization processes and applications to protoberberine alkaloid synthesis
A diethylphosphite mediated electrochemical oxidation strategy for the synthesis of 3,4-dihydroisoquinolin-1(2H)-ones from tetrahydroisoquinolines under mild conditions has been developed. This protocol provides an environmentally friendly and simple way for the construction of C=O bonds in an undivided cell unit.
