Improved Synthesis of 1,3-Propanediol Derivatives Having a Diethoxyphosphoryldifluoroethyl Functional Group at the 2-Position: Application to Chemoenzymatic Synthesis of Novel Acyclic Nucleotide Analogues of Adenosine Bisphosphates
Lipase-catalyzed enantioselective acylation of prochiral 2-(ω-phosphono)alkyl-1,3-propanediols: Application to the enantioselective synthesis of ω-phosphono-α-amino acids
Lipase PS catalyzed acetylation of prochiral 2-(omega-phosphono)alkyl-1,3-propanediols 1a-c was found to proceed with high enantioselectivity. The applications of phosphonic chirons 2a-c thus obtained were illustrated by the stereocontrolled synthesis of omega-phosphono-alpha-amino acids such as L-AP-3, L-AP-4, and N-Boc-L-F(2)Pab(OEt)(2)-OH.

Improved Synthesis of 1,3-Propanediol Derivatives Having a Diethoxyphosphoryldifluoroethyl Functional Group at the 2-Position: Application to Chemoenzymatic Synthesis of Novel Acyclic Nucleotide Analogues of Adenosine Bisphosphates
An alternative synthesis of 1,3-propanediol 1 having a diethoxyphosphoryldifluoroethyl group was examined. The method readily provided a multi-gram quantity of 1. The propanediol 1 was chemo-enzymatically transformed to acyclic nucleotide analogues for adenosine bisphosphates.
