1,4-Difunctionalized compounds RCO2(CH2)3COCOR1 (R = Me, R1 = OEt, Me, Ph; R = Ph, R1 = OEt, Me) were prepared by singlet oxygenation of cyclic vinyl ethers I. I were prepared by the cyclization of RCOCH2COR1 with Br(CH2)3Br in acetone containing K2CO3.

Key words: FUNCTIONAL GROUP, OXYGEN, ACETONITRILE, CYCLOALKENE P
