Synthesis of 14C-labelled (R)-α-amino-6,7-dimethyl-3-(phosphonomethyl)-2-quinolinepropanoic acid
摘要:
The NMDA antagonist (R)-alpha-amino-6,7-dimethyl-3-(phosphonomethyl)-quinolinepropanoic acid 1 was [C-14]-labelled at the 6-methyl group. The quinoline synthesis started from 4-bromo-3-methylaniline and the radiolabel was introduced late in the synthetic scheme. The synthesis was accomplished by a NiCl2(dppp)(2)-catalyzed coupling of the 6-bromoquinoline derivative 6 with a zinc reagent made from [C-14]-methyl iodide.
