Intramolecular photochemical addition reactions of .omega.-styrylaminoalkanes

Photoredox‐Catalyzed Site‐Selective α‐C(sp3)−H Alkylation of Primary Amine Derivatives

“…[2] Competitive N-alkylation events for primary and secondary amines can hinder the formation of aamino radicals (Figure 1a). [3] Acleavable functionality at the a-position may be pre-installed to circumvent undesired reactivity by accessing a-amino radicals (Figure 1b). [4] Hydrogen-atom transfer (HAT) catalysts have been successfully implemented to achieve a-C À Hfunctionalization of acylated secondary amine derivatives devoid of a-pre-functionalization.…”

Addition and cycloaddition reactions via photoinduced electron transfer

“…Lewis and his coworkers reported the intramolecular photoaddition of aliphatic secondary amines to arylalkenes to give 5-and 6-membered cyclic amines (Scheme 17) [66][67]. Ohashi reported that the other type of photoaddition reaction takes place when 1,4-dicyanobenzene and triethylamine are used as substrates.…”
