A variety of substituted 1-oxaspiro[4.4]non-6-ene. 1-oxaspiro[4.5]dec-6- ene, 6-oxaspiro[4.5]dec-1-ene and 1-oxaspiro[5.5]undec-7-ene systems have been prepared by utilizing Amberlyst-15-catalyzed intramolecular S(N)2' oxaspirocyclizations of secondary allylic alcohols under mild reaction conditions in quantitative yields. This oxaspirocyclization was applied to the total synthesis of theaspirane and theaspirone from β-ionone in five steps. (C) 2000 Elsevier Science Ltd.
