The same benzyl-γ-butyrolactone was synthesized from reductivehydrogenolys is of methyl thiolbenzyl diester of benzylsuccinic acid (5) or methyl thiolethyl diester of benzylsuccinic acid (10) synthesized from benzylsuccinic anhydride. Also, reductive hydrogenolysis of ethyl thiolbenzyl diester of benzylsuccinic acid (15) synthesized from β-benzilidenesuccinic acid monoethyl ester (12) of known structure gave β-benzyl-γ-butyrolactone and it was found that this was identical with the lactone prepared in the above method. Accordingly, the position of benzyl group in the above lactone must be in β-position.
