REGIOPSPECIFIC OXIDATION OF SUBSTITUTED 1-BENZYL-3,4-DIHYDROISOQUINOLINES USING SINGLET OXYGEN
Martin, Ned H.,Champion, Sidney L.,Belt, Phillip B.
, p. 2613 - 2616 (1980)
Singlet oxygen regiospecifically oxidizes 1-benzyl-3,4-dihydroisoquinoline to 1-benzoyl-3,4-dihydroisoquinoline.Mechanistic studies do not distinguish between a dioxetane or the alternative zwitterionic peroxide intermediate.
