摘要

Diastereoselective hydrophosphonylation of aldehydes with a chiral H-phosphonate is described. High asymmetric inductions were obtained using a readily available TADDOL auxiliary. Subsequent, racemization-free removal of the chiral auxiliary led to the desired alpha-hydroxyphosphonic acids in very good yields and high enantiomeric purity as the (R)-enantiomers.
