Synthesis of intermediate (XVI): The reaction of the nitrone (XIII) first with hydroxylamine and then with formic acid gives hydroxamate (XIV), which is protected with 2-(trimethylsilylethoxymethyl chloride (A), DIEA and DMAP in CH2Cl2 to affords the protected ester (XV). Finally the methyl ester group of (XV) is hydrolyzed with NaOH in THF/water to afford the acid intermediate (XVI).
