Enzymes in organic chemistry — 5: First and chemo-enzymatic synthesis of α-aminooxyphosphonic acids of high enantiomeric excess
摘要:
alpha-Acyloxyphosphonates (+/-)-5a and (+/-)-5b, derived from 3-phenylpropionaldehyde and acetaldehyde. were involved by lipase-catalyzed enantioselective hydrolysis. Three of the four chiral, non-racemic alpha-hydroxyphosphonates obtained had 99% ee. the fourth 91%. They were transformed chemically into alpha-aminooxyphosphonic acids.
