Abstract
N-Substituted a -formylglycine esters of the general formula <FORM:0592461/IV/1> or the tautomeric form <FORM:0592461/IV/2> wherein R and R1 represent alkyl or aralkyl radicals and R2 an alkyl or aryl radical, provided that when R1 is an alkyl radical R2 must be an aryl radical or a straight chain alkyl radical of 1-4 carbon atoms, are manufactured by treating an ester of the general formula R2CO.NR1.CH2.COOR with an alkyl formate in the presence of an alkali metal alkoxide, and acidifying the product. The reaction is conveniently effected in absolute alcohol, in a dry inert solvent such as ether or benzene, or in a mixture of alcohol and dry inert solvent. The esters used as starting materials may be made by treating an ethereal solution of the corresponding N-alkyl- or N-aralkyl-glycine ester with the appropriate acid chloride in the presence of an acid-binding substance, or by treating the hydrochloride of the N-alkyl- or N-aralkyl-glycine ester with the appropriate acid anhydride in the presence of the sodium salt of the corresponding acid. In examples: (1) sarcosine ethyl ester hydrochloride is treated in suspension in ether with benzoyl chloride in the presence of sodium carbonate, and the resulting ethyl N-methyl-hippurate is stirred with ethyl formate and a solution of potassium in alcohol and ether, yielding ethyl N-methyl-a -formylhippurate; (2) ethyl N-benzylhippurate is similarly prepared from ethyl benzylaminoacetate and is similarly converted to ethyl N - benzyl - a - formylhippuric ester; (3) sarcosine ethyl ester hydrochloride is warmed with acetic anhydride and sodium acetate, and the resulting N-acetylsarcosine ethyl ester is treated with ethyl formate as in (1) to produce a - formyl - N - acetylsarcosine ethyl ester; (4) the benzoyl chloride in (2) is replaced by caproyl chloride, yielding a -formyl-N-caproyl-N-benzylglycine ethyl ester. Sodium methoxide is also specified as a condensing agent.
