✦ Synopsis
Abstract
The synthesis of the trichloromethyl analogue of benzyloxycarbonyl‐threonine is described. This precursor was reduced by tritium gas to give [methyl‐^3^H~3~]‐threonine and its allo isomer. They were separated by HPLC using a chiral stationnary phase. They have a molar specific activity of 3190 GBq/mmol, 86 Ci/mmol.

Due to the desire for biological assay techniques of greater sensitivity and specificity than presently exist for the antihypertensive drug guanethidine, tritium labeled guanethidine of high specific activity was prepared for use in radioimmunoassay procedures. This drug has been labeled in other po
Thiomethylenes-3 H] CEP-1347 (5) was synthesized by the tritiation of diformyl precursor 3 with NaB 3 H 4 followed by treatment with ethanethiol. [Methyl ester-3 H] CEP-1347 ( 7) was prepared at even higher specific activity by the alkylation of precursor 6 with C 3 H 3 I.
