2-Iodophenol and 2-iodo-N-mesylaniline have been reacted with alpha-arylpropargylic alcohols of high enantiomeric purity under transition-metal catalysis leading to aryl 2-benzofuranyl and aryl 2-indolyl carbinols in good yield and high enantiomeric excess, thus constituting the first enantiospecific synthesis of these important classes of compounds.
