  By screening various chiral P,P-ligands in the palladium-catalyzed reaction of ortho-iodobenzaldehyde with allyl tributylstannane, a suitable ligand (Taniaphos) was identified that affords 3-methylene-1-indanol with an enantioselectivity of 96% ee. This result indicates that a ligated palladium intermediate is involved in the chirogenic step of the catalytic cycle (intramolecular electrophilic activation

  Asymmetric domino allylstannylation-Heck reaction of o-formylaryl triflates was successively catalyzed by Pd/ClickFerrophos to give the 3-methylene-indan-1-ols in good yields with good to excellent enantioselectivities. The benefit of the reaction is that the starting o-formylaryl triflates are prepared from easily accessible salicylaldehyde derivatives, and the variation of the product, chiral 3-methylene-indan-1-ols, can be expanded. The reaction with 4-substituted substrates gave the corresponding 3-methylene-indan-1-ols in good yields with high enantioselectivities, whereas the reaction with 5- and 6-substituted substrates occasionally afforded the corresponding Stille coupling product in significant amounts along with the desired 3-methylene-indan-1-ols.
• Enantioselective Synthesis of 3-Methyleneindan-1-ols via a One-Pot Allylboration–Heck Reaction of 2-Bromobenzaldehydes

  日期：2015.5.15

  A novel, one-pot allylboration-Heck reaction of 2-bromobenzaldehydes has been developed for the general and efficient synthesis of 3-methyleneindan-1-ols. Modification of the one-pot procedure to include chiral Bronsted acid catalyzed allylation has allowed the preparation of these building blocks in high enantioselectivity and excellent yields.
