The expedient syntheses of small libraries of ((β-ethoxycarbonyl, -cyano and -acetyl)propyloxy) methylphosphonate scaffolds bearing olefin, sulfanyl, or amine functions are described. All these new derivatives are readily produced from easily available starting reagents (aldehydes, electron-poor olefins, and dialkylphosphites) following a three steps reaction sequence of condensations, SN2′-type reaction and a conjugated thia- or aza-Michael 1,4-addition with aromatic and aliphatic thiol or amine nucleophiles.

We synthesized substituted benzaldehyde derived α-hydroxyphosphonates (αOHP), α-hydroxyphosphonic acids (αOHPA) and α-phosphinoyloxyphosphonates (αOPP) and characterized their cytotoxicity against a panel of cancer cell lines. A library containing 56 analogues was screened against Mes-Sa parental and Mes-Sa/Dx5 multidrug resistant uterine sarcoma cell lines, using a fluorescence-based cytotoxicity assay. The cytotoxicity screening revealed that dibenzyl-αOHPs and dimethyl-α-diphenyl-OPPs were the most active clusters, which encouraged us to synthesize further dibenzyl-α-diphenyl-OPP derivatives that elicited pronounced cell killing. Further structure-activity relationships showed the relevance of hydrophobicity and the position of substituents on the main benzene ring as determinants of toxicity. The most active analogs proved to be equally, or even more toxic to the multidrug resistant (MDR) cell line Mes-Sa/Dx5, suggesting these compounds may overcome P-glycoprotein mediated multidrug resistance by evading the drug transporter.
Phosphorylation of (1-aryl-1-hydroxymethyl)phosphonates

The reaction of dimethyl (1-aryl-1-hydroxymethyl)phosphonates with 1-chloro-3-phospholene 1-oxides, diphenylphosphinic chloride or diphenyl chloridophosphonate affords the corresponding (1-phosphoryloxymethyl)phosphonates. The products with two different
