## Abstract The preparation of the title compunds, using β‐ionone, is accomplished in fair overall radiochemical yield from (2‐^14^C) bromacetic acid, in 7 and 8 steps respectively. The sequence utilises ylid reactions of the phosphonoacetate derived from bromacetic ester, and is also capable of th
## Abstract The high yield, four‐step synthesis of catechol‐U‐^14^C from benzene‐U‐^14^C is described. Intermediates in the preparation include phenol‐U‐^14^C and o‐methoxyphenol‐U‐^14^C [guaiacol‐(phenyl‐U‐^14^C)].
## Abstract Radio‐labelled coenzyme Q~10~, labelled at the 3′‐position with ^14^C, was synthesized starting from natural solanesol and ethyl [3‐^14^C] acetoacetate. The radiochemical yield was 8.0% from ethyl [3‐^14^C] acetoacetate. The specific radioactivity of the product was 44.8 μCi, 1.66 MBq/m
## Abstract The synthesis of the title compound (5) is described. Treatment of mitomycin C with sodium methoxide gave decarbamoyl mitomycin C (2). Reaction with acetic anhydride in methanol yielded N1a‐acetyl‐mitomycin C (3). Treatment with [^14^C]phosgene in the presence of N,N‐dimethylaniline yie
