Abstract
Triphenyl phosphonium perchlorate (TPP) is found to be an efficient catalys t for the imino Diels-Alder reaction of aldimines with cyclopentadiene and 3,4-dihydro-2H-pyran is reported for the first time. One pot synthesis of f uroquinoline, cyclopentaquinolines and phenanthridine catalysed by TPP is a lso reported in good yields. (C) 2001 Elsevier Science Ltd. All rights rese rved.
