Destannylative acylation of 1-[(2-methoxyethoxy)methoxy]-2-(phenylsulfonyl)-2-(tributylstannyl)cyclopropane (1) provided dihydrofurans 5 in good yields, which upon treatment with BF3.OEt2 in CH2Cl2 led to the formation of 3-acylfurans 6 in moderate yields. The reaction was proposed to proceed via the intramolecular Prins-type reaction of the oxonium intermediate 7.
