Palladium-catalyzed cross-coupling of aryllithium reagents with 2-alkoxy-substituted aryl chlorides is described. The reactions proceed under mild conditions with short reaction times and provide a wide range of 2-alkoxy-substituted biaryls. This new methodology is applied to the efficient preparation of 3,3′-diaryl BINOLs and represents the first synthesis of this important class of chiral compounds from the corresponding 3,3′-dichloro BINOLs. (Chemical Equation Presented).

Different primary, secondary, and tertiary alcohols were efficiently converted to their corresponding methoxymethyl ethers with formaldehyde dimethyl acetal in the presence of catalytic amounts of ZrO(OTf)2 at room temperature. Phenols were als
A highly efficient strategy for the synthesis of 3-substituted salicylic acids by either directed ortho-lithiation or halogen-metal exchange of substituted mom protected phenols followed by carboxylation
