N-benzyloxycarbonyl-γ-tert-butyl-L-glutamic acid dicyclohexylamine salt
英文别名
dicyclohexylamine salt of γ-tert-butyl Z-glutamate;5-tert-butyl N-(benzyloxycarbonyl)-2-aminoglutarate, compound with N-dicyclohexylamine (1:1);N-Benzyloxycarbonyl-L-glutaminsaeure-5-tert.-butylester;Z-Glu(otbu)-OH dcha;N-cyclohexylcyclohexanamine;(2S)-5-[(2-methylpropan-2-yl)oxy]-5-oxo-2-(phenylmethoxycarbonylamino)pentanoic acid
In order to examine the lipotropic and hypotensive effects of glutamylcholines, α-and γ-(Z-and Boc-glutamyl) cholines (4a, 4'a, 4b and 4'b) were synthesized by the removal of the tert-butyl and benzyl groups of the corresponding tert-butyl (3a and 3'a) and benzyl (3b and 3'b) choline esters which were obtained by the esterification of tert-butyl Z-glutamates (1a and 1'a) and benzyl Boc-glutamate dicyclohexylamine salts (1b and 1'b) with N, N-dimethylaminoethyl chloride, followed by methylation with methyl halide.

The synthesis, by conventional methods, of six diastereoisomeric oligopeptides of γ-t-butyl glutamate and the polymerisation of five of them, by means of dicyclohexylcarbodi-imide in acetonitrile, are described. The resulting sequential diastereoisomeric poly-(γ-t-butyl glutamate)s had molecular weights in the range 6500–42,000.
