14C-labeled chlorogenic acid (specijic activity 30.6 nCilmg) was synthesized by reaction of diphenylmethyl-I-0-ethoxy-carbonyl- 4,5-0-isopropylidenequinate ( V ) with 0,O-dimethylcarbonyl caffeoyl chloride-u-14C (VIII) followed by selective hydrolysis of the protecting groups.

## Abstract Condensation of aromatic carboxaldehydes with [2‐^14^C]‐__malonic acid under Knoevenagel conditions provides corresponding β‐aryl substituted__ [α‐^14^C]‐acrylic acids. The reaction is applicable to both aromatic and heteroaromatic aldehydes under controlled reaction conditions leading
## Abstract A widely used herbicide, 2,2‐dichloropropionic acid (dalapon), was synthesized with ^14^C‐labeling in the C‐1 or C‐2 positions. The carboxyl labeled material was prepared in 55% yield by carbonation of 1,1‐dichloro‐ethyllithium at approximately −104°. Starting with trichloroacetic acid,
## Abstract Dimethoxymethyl phenobarbital (DMMP), labeled with ^14^C on the ring and side chains was prepared for drug metabolism studies. The synthesis of DMMP‐ethyl‐1–^14^C (4a) in four steps provided a 43% yield from ethyl‐1–^14^C iodide. The yields of DMMP‐2–^14^C (4b) and DMMP‐dimethylene‐^14^
The synthesis of 14C-labeled menthol was accomplished by preparation of 14C-labeled (&) pulegone. Catalytic hydrogenation and chemical reduction converted (&) pulegone to the isomeric menthols possessing 1.10 mCi total activity. Gas chromatographic separation of this material gave the relative abund
