The spontaneous cyclodimerization of 2,3-dihydroisoquinolines after base promoted elimination of methanol from 4-methoxy-1,2,3,4-tetrahydroisoquinolines

The reaction of 4-methoxy-1,2,3,4-tetrahydroisoquinolines I (R = MeO, R1 = H; RR1 = OCH2O) with Li diisopropylamide affords dimerization products II. The intermediacy of orthoquinodimethanes and diradicals is assumed. [on SciFinder (R)]
