Abstract: | A new, mild and high yielding synthesis of phosphoramidates is described: potassium salts of carboxylic acids are treated with ethylchloroformate and the resulting activated anhydride-carbonates are then treated with LiNH-P(O)(OEt)2 in situ--the methodology is especially suited to acid sensitive systems featuring BOC, tBu or acetal protecting groups. |
