Abstract

Optically active N-(tert-butoxy-carbonyl) -o-benzyl-serine and N-(tert-butoxy-carboxyl) -o-benzyl-threonine and their salts with bases are prepd. by acylating optically active serine or with tert-butenyl-carbonate in the presence of an alkali-hydroxide to obtain optically active N-(tert-butoxy- carmrbonyl-)-serine, or -threonine. These are benzylated in the presence of an alkali-hydroxide, in the reaction mix with benzyl-chloride, at 5-15 deg.C. Both reaction steps are performed in anhydr. di:methyl-sulphoxide. Products are isolated as free acids or as their alkali salts
