A modified stereospecific synthesis of potentially biologically and pharmacologically active methyl (1R,2R,3E,5R)-3-(hydroxyimino)-5-methyl-2-(1-methylethyl)cyclohexanecarboxylate from (R)-4-menthen-3-one was developed using sequential 1,4-conjugate addition of Norman reagent catalyzed by CuI–BF3⋅Et2O–CuCl2 and ozonolysis–reduction of the intermediate (R,R,R)-vinylmenthone by hydroxylamine hydrochloridein MeOH.
