Abstract
Acyloxiranes react with cyclopentanone and cyclohexanone in the presence of catalytic amounts of boron trifluoride etherate to give the corresponding 2-acyl-1,4-dioxaspiro[4,4]-nonanes and 2-acyl-1,4-dioxaspiro[4,5]decanes. The corresponding cis-2,3-dimethyl-2 acetyl-1,4-dioxaspiroalkanes are formed from trans-2,3-dimethyl-2-acetyloxirane.
