Synthesis of the four enantiomers of diethyl 1,2-di(N-Boc-amino)propylphosphonates
摘要:
A simple and efficient synthetic strategy to all four enantiomerically pure diethyl 1,2-di(N-Boc-amino) propylphosphonates has been elaborated starting from the corresponding N-[(R)-(1-phenylethyl)]aziridine-(2S)- and N-[(S)-(1-phenylethyl)]aziridine-(2R)-carboxaldehydes, employing a one-pot three-components Kabachnik-Fields reaction followed by the hydrogenolytic removal of the chiral auxiliary and aziridine ring opening with simultaneous protection of the amino groups as the N-Boc derivatives.

Chiral contiguous bisaziridines were prepared by the aziridination of chiral 3-[1-(1-phenylethyl)aziridin-2-yl)]acrylaldehydes with either N-Boc-O-tosyl or N-Ts-O-tosyl hydroxylamine as a nitrogen source and (2R)- or (2S)-[diphenyl(trimethylsilyloxy)methyl]pyrrolidine as a chiral organocatalyst. The regioselective ring opening of bisaziridines afforded chiral nitrogen-rich molecules.
