Abstract
Abstract A series of derivatives of 2-aminopyrroline (2-iminopyrrolidine) and neopentylene-, pyrocatecholphosphorous and diisopropylphosphinous acids 5, 11-13, 17, 19 has been synthesized. It was established that P(III)-phosphorylated 2-aminopyrrolines have different structures depending on nature of substituent at the exocyclic N atom: with R[dbnd]Me phosphite 11 is preferably in aminopyrroline form A, with R[dbnd]Ph phosphite 17 is in the iminopyrrolidine form B. The structure of the obtained compounds was studied by means of 1H, 13C, 15N and 31P NMR spectroscopy.
