Interaction of magnesium indolates and allyl oxides in the presence of bis (tripheny1phosphine) nickel dichloride results in indole P-allylation, except in cases involving highly substituted indoles and allyl alcohols. This method permits the@- prenylation of indole and a-prenylation of ketones (by way of their magnesium enaminates). Base-induced interaction of ethynyldimethylcarbinyl chloride and indole under a variety of ...
