1-(Tributylstannyl)-2-alkene reacts with a solution of an aldehyde and BuSnCl3 to give (Z)-homoallylic alcohol. Z-Selective 2-methyl-2-butenylation can be accomplished by using (Z)-2-methyl-1-(tributylstannyl)-2-butene instead of 1-(tributylstannyl)-2-alkene. This reaction is useful as a new method to make (Z)-double bond. An application of the present method for a synthesis of pheromones is also described.
