The addition of stabilized phosphorus anions to aldehydes leads to α-substituted β-hydroxyphosphonates. The diastereoselectivity of the process is strongly influenced by the substitution of the phosphorus atom. Whereas P-ethyl derivatives provide a mixtur

Chiral oxazaphosphorinanes, derived from (-)-8-amino menthol are alkylated with good to excellent diastereoselectivities. The regioselectivity in the alkylation is dependent on the base used for deprotonation. The ethyl oxazaphosphorinanes are alkylated a
Base-dependent regio- and diastereoselective alkylation of chiral perhydro 1,3,2-oxazabenzophosphorinane-2-oxides derived from (-)-8-benzylamino menthol

The regioselectivity in the alkylation of chiral perhydro 1,3,2-benzoxazaphosphorinane-2-oxides is dependent on the base used for deprotonation. The ethyl oxazaphosphorinanes are benzylated at the nitrogen substituent after deprotonation with n-BuLi, but
