摘要：

Theoretical studies on the Staudinger reaction between methoxyketene and a simple imidate provide an explanation for the trans stereoselectivity observed. The key step responsible for this unusual outcome is the facile interconversion between two zwitterionic intermediates through a biradical transition state.
