A novel reaction for the functionalization of epoxy resins: New regio- and chemoselective ring-opening of epoxides with aryl silyl ether catalyzed by cesium fluoride

Nambu,Endo

, p. 1723 - 1726 (2007/10/02)

By use of cesium fluoride as a catalyst, aryl or alkyl glycidyl ethers were ring-opened by aryl trimethylsilyl ether to produce O-protected aryloxyhydrins with a quantitative regioselectivity for the first time. Alkyl silyl ether was ineffective for this ring-opening.
