Water and ethyl diazoacetate were found to be matched components for generating highly reactive nucleophilic oxonium ylide in the presence of a dirhodium acetate catalyst. Simultaneous trapping of the oxonium ylide intermediate with aryl imines gave β-aryl isoserine derivatives with high diastereoselectivity.
