α-Hydroxy-lactams formed by reduction or Grignard addition to appropriately N-substituted phthalimides (1a-d) undergo acid-catalysed cyclodehydration to derivatives of the isoindolo-fused heterocyclic systems (6)-(10).Ring closures to the naphthalene 2- or 8-position are observed to occur with N-1-naphthylalkyl substituents, the latter proved by an X-ray crystal structure determination of 13b-phenyl-7H-benzisoindoloisoquinolin-9(13H)-one (9b).
