Development of a Phase-Transfer-Catalyzed, [2,3]-Wittig Rearrangement
摘要:
An investigation into the use of phase-transfer catalysis for the [2,3]-sigmatropic rearrangement of allyloxy carbonyl compounds is described. Initial studies focused on identifying viable substrate classes that would undergo selective [2,3]-rearrangement under phase-transfer catalysis. Under certain conditions, the [2,3]-sigmatropic rearrangement of allyloxy carbonyl compounds takes place in the presence of a phase-transfer agent, providing a rare example of a phase-transfer-catalyzed unimolecular reaction. In the course of this investigation, it was found that catalysis is dependent on several variables including base concentration, catalyst structure, and substrate lipophilicity. Preliminary testing of chiral, nonracemic phase-transfer catalysts has shown promising levels of enantioselectivity for future development.
