2) The esterification of 2(R)-[4-oxo-3(S)-[1(R)-(trimethylsilyloxy)ethyl]azetidin-2(S)-yl]propionic acid (X) with the previously obtained pyrrolidinone (V) gives the expected thiopropionic ester (XI), which is acylated with oxalic acid monochloride monopivaloyloxymethyl ester (XII) by means of trimethylsilylchloride and triethylamine yielding the condensation product (XIII). The cyclization of (XIII) by means of methylphosphonic acid diethyl ester affords silylated CS-834 (XIV), which is finally deprotected with 1N HCl.
