Cationic hetero cyclization

Scheme 1.48. Cationic domino cyclization/hetero-Diels-Alder procedure. Scheme 1.48. Cationic domino cyclization/hetero-Diels-Alder procedure.
Cationic hetero [4 + 2] cyclization has been performed with TiCl4-PPh3 as Lewis acid. Equations (154) and (155) show that the process probably proeeeds in a con-eerted path to give the corresponding products with excellent stereospeeificity [397]. [Pg.719]
