Synthesis of 2,2-Diphenyl-3-oxetanol Derivatives and Their Thermal or Acid-catalyzed Decomposition

Shimizu, Nobujiro,Yamaoka, Shintaro,Tsuno, Yuho

, p. 3853 - 3854 (2007/10/02)

A series of five different 2,2-diphenyl-3-oxetanols was synthesized by photocycloadditiion of benzophenone and enol trimethylsilyl ethers followed by protolysis of the resultant 3-trimethylsiloxyoxetanes.Thermal cleavage and acid-catalyzed rearrangement of these oxetanes are described.
