    Catalytic Enantioselective Synthesis of α-Aminooxy and α-Hydroxy Ketone Using Nitrosobenzene
    摘要:
    The highly enantioselective and O-selective nitroso aldol reaction of tin enolates 2 and nitrosobenzene (1) has been developed with the use of (R)-BINAP-silver complexes as a catalyst. After the various silver salts were surveyed, the AgOTf and the AgClO4 complex were found to be optimal in the O-selective nitroso aldol reaction in both asymmetric induction (up to 97% ee) and regioselection (O/N = >99/1), affording aminooxy ketone 3. The product 3 can be transformed to alpha-hydroxy ketone 5 without any loss of enantioselectivity. Thus, the method provides an efficient approach to the catalytic enantioselective introduction of oxygen alpha- to the carbonyl group.

  • Aromatic reactivity. Part XXXV. Alkali cleavage of aryltrimethylstannanes: an unusual electrophilic aromatic substitution
    作者:C. Eaborn、H. L. Hornfeld、D. R. M. Walton

    We have measured spectrophotometrically the rates of cleavage by aqueous methanolic alkali of the aryl–tin bonds in a series of X·C6H4·SnMe3 compounds. In this reaction, the rate-determining step of which probably involves separation of the carbanion X·C6H4–, the effects of meta substituents are in accord with the Hammett σ constants (σ= 2·18), but the effects of para substituents show an abnormal
    我们通过分光光度法测量了一系列X·C 6 H 4 ·SnMe 3化合物中芳基-锡键的甲醇碱水溶液的裂解速率。在该反应中,确定速率的步骤可能涉及分离碳负离子X·C 6 H 4 –,间位取代基的作用与Hammettσ常数(σ= 2·18)一致,但对位取代基显示异常图案。例如,不仅通过诸如p -CF 3和p -Cl的吸电子基团,而且通过诸如p -OMe和p -NMe 2。对于对位取代基时,效果大致与它们线σ 1周的常数。
