摘要：

A simple and efficient methodology to construct C-11-labeled olefins (5) was developed. The method involves two different C-C bond-forming reactions: C-11-methylation of a phosphonate (2) using [C-11] methyl iodide (1) and subsequent HWE reaction of C-11-methylated phosphonate (3) with aldehydes (4). Tetrabutylammonium fluoride promoted both C-C bond-forming reactions efficiently as a base. This sequential reaction was conducted in one pot. A wide variety of alpha-[C-11] methyl-alpha,beta-unsaturated compounds were prepared by changing the substituents on the phosphonate and the aldehyde.
