  • Hydroxoiridium/Chiral Diene Complexes as Effective Catalysts for Asymmetric Annulation of α-Oxo- and Iminocarboxamides with 1,3-Dienes
    作者:Miyuki Hatano、Takahiro Nishimura
    DOI:10.1002/anie.201505382
    日期:2015.9.7
    The asymmetric [3+2] annulation of α‐oxo‐ and α‐iminocarboxamides with 1,3‐dienes catalyzed by hydroxoiridium/chiral diene complexes was realized, giving high yields of the corresponding γ‐lactams with high enantioselectivity.

    日期:——
    Enantioselective [3 + 2] annulation between 1,3-dienes and N-acyl ketimines in situ generated from 3-aryl-3-hydroxyisoindolin-1-ones proceeded via C–H activation to give spiroaminoindane derivatives in high yields with high regio- and enantioselectivity, which is realized by use of an Ir/chiral diene catalyst.

    to give 1‐aminoindane derivatives in high yields with high regio‐ and stereoselectivities. The iridium complex coordinated with a substrate 1,3‐diene displayed high catalytic activity. The reaction proceeds via the direct formation of the aryliridium(I) species from the aromatic aldimine and an iridium(I) acetate species via a concerted metalation‐deprotonation pathway.

  • Autoxidative decarbonylation of a stable enol from Diels–Alder addition of 2-methoxy-5-methylbenzoquinone to sorbic acid esters

    日期:——
    The reaction of 2-methoxy-5-methylbenzoquinone (1) methyl sorbate (2a) gives mainly the enol, the Diels–Alder adduct (5a), which undergoes oxidative ring-cleavage via the hydroperoxide (7a) to give the β-ketoester (8a) in a good yield.

  • One-flask, regiospecific conversions of allylic alcohols into 2-carbon-extended, conjugated dienoate esters. Use of a new sulfinyl orthoester
    作者:Gary H. Posner、R. David Crouch、Chris M. Kinter、Jean Christophe Carry
    DOI:10.1021/jo00025a008
    日期:1991.12
    Sixteen differently substituted primary and secondary allylic alcohols are shown to react with sulfinyl orthoacetate 1 at 100-degrees-C sequentially via a [3,3] sigmatropic rearrangement and then a beta-elimination of benzenesulfenic acid to form conjugated dienoate esters 5-13 in 45-95% yields. This one-flask, intramolecular carbon-carbon bond-forming process represents a simple and convenient method for regiospecific gamma-attachment of a two-carbon (ethoxycarbonyl)methylene unit via the synthetic equivalent of an S(N)2' process. Two examples are given in which rationally designed dienoates 20 and 24, prepared via this one-flask process and carrying a pendant alkene unit, undergo intramolecular 2 + 4 cycloaddition producing bicyclic cyclohexenes 21 and 25.
