Structural elucidation of the cyclic products formed by the reaction of 2,3-O-isopropylidene derivatives of aldehydo-aldose with allylsilanes, vinyl ethers, or vinyl sulfides in the presence of boron trifluoride etherate

Sugimura

, p. 5909 - 5912 (2007/10/02)

The structural elucidation of the cyclic products derived from 2,3-O-isopropylidene derivatives of aldehydo-aldose and allylsilanes, vinyl ethers, or vinyl sulfides indicated that tetrahydrofuran derivatives were formed by cyclization accompanied with migration of the isopropylidene group.
