Synthesis of four stereoisomers of protected 1,2-epiimino-3- hydroxypropylphosphonates
Wroblewski, Andrzej E.,Drozd, Joanna
, p. 200 - 206 (2011)
Enantiomerically pure protected 1,2-epiimino-3-hydroxypropylphosphonates were synthesised from hydroxy-1-{[(R)- or (S)-1-phenylethyl]aziridin-2-yl} methylphosphonates via regioselective ring opening with acetic acid followed by a stereospecific intramolec
