8synthesis methods
-

Yield:2788-84-3 98%

Reaction Conditions:

with thionyl chloride

Steps:


Following the synthetic route depicted below the L-amino acids were treated with methanol and sulfoxide chloride to convert into the corresponding L-amino acid methyl esters II (98% yield) in the present invention. The methyl esters IIa-d were acylated by use of benzoyl chloride and N-benzoyl-L-amino acid methyl esters of IIIa-d were obtained (81% yield). Using sodium borohydride as the reduction agent the benzoylated methyl esters were reduced to N-benzoylaminoglycols IVa-d successfully (97% yield).
