  日期：——

  A nickel-catalyzed asymmetric Suzuki–Miyaura cross-coupling of racemic 3-bromo-phthalides and arylboronic acids was realized for the synthesis of diverse chiral 3-aryl-phthalides in moderate to excellent reaction yields. The reaction proceeded in a stereoconvergent manner and high enantioselectivities were observed for most examined examples. A number of functional groups like aldehyde, ester and bromide

  sequential addition of silyl cyanide and ketene silyl acetals to esters was achieved by a gallium trihalide catalyst to produce β‐cyano‐β‐siloxy esters. This is the first example of the sequential addition of two different carbon nucleophiles to esters. The employment of lactones provided α,α‐disubstituted cyclic ethers with a cyano group and an ester moiety. A variety of esters and lactones are applicable

  A one-pot synthesis of new 3-benzylphthalide derivatives was developed by using a strategy based on tetrakis(dimethylamino)ethylene (TDAE). The reactions in the presence of TDAE of substituted benzyl chlorides with methyl 2-formylbenzoate or of substituted methyl-2-formylbenzoates with 4-nitrobenzyl chloride furnished the corresponding isobenzofuran-1(3H)-one products in moderate to good yields.
