strategies for the synthesis of these compounds, carbon isotopes in particular, are needed due to the limited availability of labelled reagents. We have developed a novel method for the 14C labelling of enones and have applied it to the synthesis of a 14C radiolabelled version of the cholesterol absorption inhibitor CP-148,623. The key steps involve the 1,2 addition of [14C]methyl Grignard to a cyclic
