Amberlyst-15–Catalyzed Efficient Cyclization of γ- and δ-Unsaturated Alcohols: Green Synthesis of Oxygen Heterocycles
摘要:
Amberlyst-15 (H+) resin catalyzes efficient cationic endo-cyclization of - and -unsaturated alcohols to yield tetrahydro-(2H)-pyrans and oxepanes. The merits of the present protocol are good yield of the products under mild conditions, simple workup, and reusability of the resin.
