    Stereoselective reduction of the ketone group in α-allyl β-keto esters
    摘要:
    Stereoselective reduction of the ketone carbonyl group in alpha-allyl-substituted beta-keto esters with sodium tetrahydridoborate in the presence of 2 equiv of MnCl2 quantitatively afforded the corresponding syn-isomeric alcohols. The reduction of the same substrates with L-selectride [LiBH(s-Bu)(3)] in anhydrous THF was characterized by low chemoselectivity, and anti-isomeric alcohols were formed in about 50% yield. Under analogous conditions, alpha-allyl ketones smoothly reacted with L-selectride to give syn-isomeric alcohols in quantitative yield. The corresponding anti isomers were synthesized by the Mitsunobu reaction of the syn isomers with formic acid, followed by alkaline hydrolysis.

    日期:2004.11
    The Prins cyclization of an aldehyde 1 with a homoallylic alcohol 2, affording tetrahydro-2H-pyrans 4via the oxonium ion 3 as central intermediate, was conceptually transferred to (alk-3-enyloxy)acrylates 6, which form a related oxonium ion 7 upon treatment with acids (Scheme 1). The scope and utility of this modification of the Prins-type cyclization of oxonium ions is discussed exemplarily by means
