The expedient syntheses of small libraries of ((��-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. |
