Collidine p-toluenesulfonate

Cyclization of enynones to methylenecyclopentenones. This cyclization can be effected under thermal conditions, particularly in the case of activated (Z)-enynones, but in only moderate yield. Some acceleration is observed with reagents known to promote enolization (LiCl and collidine p-toluenesulfonate), but dramatic effects can be obtained with phenols such as 1. Vitamin E is marginally more... [Pg.54]
