  • Computationally Guided Organometallic Chemistry:  Preparation of the Heptacyclic Pyrazine Core of Ritterazine N
    作者:Douglass F. Taber、Karen V. Taluskie
    DOI:10.1021/jo052656m
    日期:2006.3.31
    Diels−Alder cycloaddition of 10 followed by Wittig homologation and intramolecular diene cyclozirconation of the resulting triene under equilibrating conditions led to the tricyclic 6−6−5 ketone 5 with high diastereocontrol. The derived α-azido ketone 16 cyclized efficiently to the heptacyclic pyrazine core of ritterazine N.

  • Chemoenzymatic deracemization of (±)-2,2-disubstituted oxiranes
    作者:Romano V.A. Orru、Sandra F. Mayer、Wolfgang Kroutil、Kurt Faber
    DOI:10.1016/s0040-4020(97)10338-6
    日期:1998.1
    The preparation of vicinal diets in up to 98% e.e. and 98% yield from the corresponding (+/-)-2,2-disubstituted epoxides was achieved via an enantioconvergent two-step hydrolysis: Thus, enantioselective enzymatic hydrolysis of the (S)-epoxide proceeded with retention of configuration furnishing the corresponding (S)-diol. In a subsequent step, the remaining (R)-oxirane was hydrolyzed during workup under acid catalysis with complete inversion of configuration yielding the (S)-diol. A detailed study of the latter reaction revealed that the experimental conditions have to be carefully chosen with respect to (i) nature of the acid, (ii) the solvent, and (iii) its water content to avoid racemization.

  • Syntheses with Organoboranes. XI. Allylboration of Vinylic Epoxides with Allylic Dialkylboranes
    作者:Marek Zaidlewicz、Marek P. Krzemiński
    DOI:10.1021/ol006641g
    日期:2000.11.1
    Allylboration of representative vinylic epoxides with allyldiethylborane (1) and (2-cyclahexenyl)dicyclohexyl borane (2) affords the corresponding 1,2- and 1,4-addition products. cis-1,2-Addition is favored in the reaction of 1 with 3,4-epoxycycloalkenes of six- to eight-membered rings. 3,4-Epoxycyclopentene (3a) and 5,5-dimethyl-3,4-epoxycyclopentene (3b) undergo five-membered ring opening during allylboration with 1 and 2, producing the corresponding (Z)-trienols (4a and 4b) with high stereoselectivity. 1,4-Addition of 1 and 2 to monoepoxides of 1,3-butadiene and isoprene is favored, producing predominantly the corresponding (E)-alcohols.
