| Abstract: | The reaction of 2-substituted 4-oxo-5, 6-benzo-1, 3, 2-dioxaphosphorinanes with ethyl pyruvate affords ring-expansion products, i.e., diastereomeric 2-substituted 2, 5-dioxo-6, 7benzo-1, 3, 2-dioxaphosphepanes.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 3, pp. 565–567, March, 1993.The authors are grateful to Ye.I.Gol'dfarb for recording the 31P-(1H) NMR spectra. |
