synthesized SM–Chol conjugates with functionally designed linker portions to restrain Chol mobility and examined their formation of orderedmembranes by a detergent insolubility assay, fluorescence anisotropy experiments, and fluorescence‐quenching assay. In all of the tests, membranes prepared from the conjugates showed properties of ordered domains comparable to a SM–Chol (1:1) membrane. To gain insight

cyclopropylmethylcarbinyl tosylate participate in organocuprate substitution reactions; retention of configuration at the nucleofugal sp3-C atom and skeletal reorganizations are observed. A plausible mechanism for these reactions is discussed. Coupling of homogeranyl iodide with a four-carbon, functionalized, vinylic cuprate reagent is applied to stereospecificsynthesis of trans, trans-farnesol.
