摘要
Herein, we disclose that carboxylate phosphabetaine can act as a competent organocatalyst for promoting the intramolecular ring opening of oxetanes, delivering oxazolidin-2-ones in good to excellent yields. 1H NMR studies and DFT calculations revealed that the carboxylate moiety of the phosphabetaine not only acts as a proton shuttle, but also provides crucial hydrogen bonding for the activation of the oxetane ring.
