The Cu(I)-catalyzed ring-opening cross-coupling of oxabicyclic olefins I (R = H, 6,7-di-Me, 5,8-dimethoxy, 6,7-dibromo, etc.) with organoboron reagents ArB(-OCH2C(Me)2CH2O-) (Ar = 4-chlorophenyl, 1-methyl-1H-indol-5-yl, naphthalen-2-yl, etc.) and phenylboronic acid pinacol ester provides access to cis-2-aryl-1,2-dihydronaphthalen-1-ol derivatives II, in contrast to the exclusive trans-selectivity in related Cu-catalyzed reactions with Grignard reagents. DFT calculations suggest that the reaction possibly proceeds via boronic ester byproduct assisted ring-opening as an alternative pathway to the canonical β-oxygen elimination as the rate-determining step. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1Product Details of 1003858-50-1).
2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Product Details of 1003858-50-1
