摘要:
1-Benzyloxyiminophosphonates (3) were converted under very mild conditions to the corresponding phosphonyl dichlorides (5). The application toward the synthesis of diastereomeric 1,3,2-oxazaphospholidines (6/7), and diastereomeric 1,3,2-dioxaphosphorinanes (8/9) is reported. The structure of 9a was confirmed by X-ray analysis.
