摘要： An industrially suitable process for preparing V-28-3M useful as an antimycotic agent by conducting methyl esterification of V-28-3 efficiently. V-28-2 is efficiently converted into V-28-3M by protecting the amino group of the amino sugar of V-28-3 with an appropriate protecting group, subjecting the carboxyl group of V-28-3 to methyl esterification with methyl methanesulfonate or methyl p-toluenesulfonate in the presence of a base, and deprotecting the N-protected intermediate.

摘要： A method for resolving optically impure 3-oxa-2-oxobicyclo�3.1.0!hexane-1-carboxylic acid esters. A method is provided for producing a 1-alkoxycarbonyl-2-hydroxymethylcyclopropane-1-carboxylic acid.N-benzyl-.alpha.-phenylethylamine diastereomer salt. An enantiomer of N-benzyl-.alpha.-phenylethylamine is reacted with a 1-alkoxycarbonyl-2-hydroxymethylcyclopropane-1-carboxylic acid to produce a precipitate that is enriched in one diastereomer of the salt. After isolating the optically active salt, the N-benzyl-.alpha.-phenylethylamine may be separated to produce the corresponding 1-alkoxycarbonyl-2-hydroxymethylcyclopropane-1-carboxylic acid. Under acidic conditions, the carboxylic acid and hydroxyl groups undergo ring closure to afford the optically active 3-oxa-2-oxobicyclo�3.1.0!hexane-1-carboxylic acid ester.
