[ 1 ] - A convenient method for 14C-labeling of N-(7-chloro-1- methyl-2-oxo-5-phenyl-2,3-dihydro-1Hbenzo[ e][1,4]diazepin-3-yl)thiophene-2-carboxamide as CCK-A antagonist
N-(7-chloro-1-methyl-2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]diazepin-3-yl)thiophene-2 carboxamide-[14C-carboxy] was prepared as part of a 6-step sequence from thiophene-2-carbonitrile -[cyano-14C] as a keysynthetic intermediate which has been synthesized from 2-iodothiophene and zinc [14C]-cyanide in thepresence of tetrakis (triphenylphosphine) palladium.
[ 2 ] - Convenient method for synthesis of a carbon-14 analogue of DL-Phenyl alanine
DL-Phenyl alanine labeled with carbon-14 in the α-position has been synthesized from ethyl[2-14C] acetate as part of a 6-step sequence.
[ 3 ] - Synthesis of a carbon-14 analogue of N-(aryl-methyl)-3-phenyl-acryl amidine-[carboxy-14C] and its derivatives as NR2B-selective NMDA receptor antagonist
Four amidine NR2B-selective NMDA receptor antagonists, N-( 2-methoxy benzyl) -3-phenyl-acrylamidine, N-[diduterio(2-methoxyphenyl) methyl]-3-phenyl-acrylamidine, N-benzyl-3-phenyl-acryl amidine and N-[diduterio(phenyl)methyl]-3-phenyl-acrylamidine, all fourlabeled with carbon-14 in the 1-position, have been synthesized as part of 5-step sequence fromBa14CO3.
