    摘要:
    Treatment of the di-2-[(IS)-1-(methylthio)ethyl]phenyl diselenide with bromine and silver triflate afforded the corresponding selenyl triflate which was used in situ as a strongly electrophilic selenium reagent to effect the asymmetric synthesis of oxygen- or nitrogen-containing heterocycles. Cyclic ethers, lactones, lactams or N-protected pyrrolidines have been prepared in good yield with complete regioselectivity and high diastereoselectivity. (C) 2001 Elsevier Science Ltd.

    Highly efficient 1,7-asymmetric induction was achieved in DIBAL-H reduction and Grignard reaction of γ-keto esters of podand-type 1,1′-binaphthalen-2-ol derivatives bearing an appropriate oligoether group as the 2′-substituent. Thus, the DIBAL-H reduction of keto esters 4 in dichloromethane–toluene at –78 °C in the presence of an excess of MgBr2·OEt2 afforded, after further reduction of the resulting

    syntheses of γ-butyrolactones. In one synthesis, Grignard addition, cleavage and reduction to carbinols RR'C(OH)CH2OH is followed by tosylation, malonate homologation, lactonization, and removal of the carbomethoxy group to give optically active γ-lactones. A modification of this synthesis (Scheme I) leads to optically active α-methylene-γ-lactones. In the second synthesis, reaction of a bromomagnesium enolate
