Iridium-catalyzed [3+2] annulation of 1,3-dienes with ortho-carbonylated phenylboronic acids. A catalytic process involving regioselective 1,2-addition
Annulation of 1,3-dienes with 2-formylphenylboronic acid proceeded with high regio- and stereoselectivity in the presence of a hydroxoiridium catalyst to give high yields of indanol derivatives. Various 1,3-dienes bearing electron-withdrawing and -donating substituents were successfully used under the catalytic conditions.
