Under carefully chosen working conditions (solvent, temp.), methyltitanium reagents smoothly convert homoallyl alcs. having a terminal double-bond into (E)-3-penten-1-ols, whereas nonterminal 3-alken-1-ols afford 4-methyl-branched derivs. with configurational inversion of the chain. Stereoselectivities were >99%. [on SciFinder (R)]
Alkynes are found in a multitude of natural or synthetic bioactive compounds. In addition to the capacity of these chemical motifs to impact the physicochemical properties of a molecule of interest, the well-established reactivity of alkynes makes them ...
