摘要

Prochiral dialkylacetal derivatives of 3-hydroxy-2-hydroxymethylpropanal 6a-e were synthesized from the corresponding 2-substituted diethyl malonates 5a-e and subjected to asymmetric enzymatic acetylation. The diethyl malonates 5a-f were prepared from diethyl chloromethylenemalonate 3 by using either a one-or a two-step process. Asymmetric acetylation of 3-hydroxy-2-hydroxymethylpropanal diethyl acetal 6b with several enzymes ...
