  • π-Cyclizations of α-methoxycarbonyl oxycarbenium ions; synthesis of oxacyclic carboxylic esters
    作者:Lucie D.M. Lolkema、Henk Hiemstra、Cindy Semeyn、W.Nico Speckamp
    DOI:10.1016/s0040-4020(01)85238-8
    日期:1994.1
    Acid-mediated cyclization reactions are described of seven methyl 2-acetoxy-2-(3-alken-1-oxy)acetates with different chain substitution. The major product of the tin tetrachloride-induced cyclization reaction is in most cases a tetrahydropyran containing an equatorial carbomethoxy function at C2 and an axial chlorine atom at C4. The mechanism of its formation involves a net cis-addition of the intermediate alpha-ester oxycarbenium ion to the carbon-carbon double bond, most likely caused by a quasi axial orientation of the ester function in a chair-like transition state. The results are interpreted by invoking (1) the occurrence of a 2-oxonia-Cope rearrangement and (2) the participation of the ester function in the mechanism of cyclization by trapping the cyclic cationic intermediate. The cyclizations of two methyl 2-acetoxy-2-(4-alken-1-oxy)acetates and two methyl 2-acetoxy-2-(alkynoxy)acetates are also described .

  • Resolution of methyl cis-3-chloromethyl-2-tetrahydrofurancarboxylate via enzymatic hydrolysis

    Kinetic resolution via enzyme catalyzed hydrolysis under neutral conditions was successfully applied to racemic methyl cis-3-chloromethyl-2-tetrahydrofurancarboxylate (1). The highest selectivities were attained with the enzymes acylase-I(E = 51) and α-chymotrypsin (E = 28). The optically active methyl ester recovered in both cases was (+)-(2S,3R)-1. The hydrolysis product spontaneously cyclized under
