Several phosphoserine and phosphothreonine synthons suitable for the stepwise synthesis of phosphopeptides have been prepared.Treatment of methylthiomethyl (MTM) esters of either benzyloxycarbonyl (Z), tert-butyloxycarbonyl (Boc) and allyloxycarbonyl (Alloc) serine and/or threonine with phosphochloridate in pyridine, followed by MgBr2 cleavage of MTM in diethylether, afforded the title compounds in excellent yields.

t-Butyl bromide-activated dimethyl sulphoxide reacted with carboxylic acids and differently N-protected amino-acids in the presence of a base (NaHCO3 or Et3N).High to quantitative yields of methylthiomethyl (MTM) esters were obtained in all cases without interference by other functional groups or racemization.The mechanism of the reaction is discussed on the basis of the products formed, of spectral data, and of other miscellaneous experiments.
