• Synthesis of the Epoxyquinol Dimer RKB-3564 D:  Utilization of an Alkoxysilanol To Promote [4 + 4] Dimerization
  作者：Chaomin Li、John A. Porco

  DOI：10.1021/ja039543+

  日期：2004.2.1

  The synthesis of the epoxyquinol dimer RKB-3564 D (3) is reported, employing an alkoxysilanol protecting group to redirect the inherently favored [4 + 2] dimerization of 2H-pyran monomers to a [4 + 4] manifold. Preliminary mechanistic studies indicate that the [4 + 4] dimerization may occur through a stepwise, ionic process.
• Different Reaction Modes for the Oxidative Dimerization of Epoxyquinols and Epoxyquinones. Importance of Intermolecular Hydrogen-Bonding

  An oxidative dimerization reaction, involving the three successive steps of oxidation, 6pi-electrocyclization, and Diels-Alder reaction, has been experimentally and theoretically investigated for the three 2-alkenyl-3-hydroxymethyl-2-cyclohexen-1-one derivatives epoxyquinol 3, epoxyquinone 6, and cyclohexenone 10. Of the sixteen possible modes of the oxidation/6pi-electrocylization/Diels-Alder reaction cascade for the epoxyquinone 6, and eight for the cyclohexenone 10, only the endo-anti(epoxide)-anti(Me)-hetero and endo-anti(Me)-hetero modes are, respectively, observed, while both endo-anti(epoxide)-anti(Me)-hetero and exo-anti(epoxide)-anti(Me)-homo reaction modes occur with the epoxyquinol 3. Intermolecular hydrogen-bonding is found to be the key cause of formation of both epoxyquinols A and B with 3, although epoxyquinone 6 and cyclohexenone 10 both gave selectively only the epoxyquinol A-type product. In the dimerization of epoxyquinol 3, two monomer 2H-pyrans 5 interact with each other to afford intermediate complex 28 or 29 stabilized by hydrogen-bonding, from which Diels-Alder reaction proceeds. Theoretical calculations have also revealed the differences in the reaction profiles of epoxyquinone 6 and cyclohexenone 10. Namely, the rate-determining step of the former is the Diels-Alder reaction, while that of the latter is the 6pi-electrocyclization.
• Novel non-peptide inhibitors targeting death receptor-Mediated apoptosis

  We have previously reported that ECH, (2R, 3R, 4S)-2,3-epoxy-4-hydroxy-5-hydroxymethyl-6-(1E)-propenyl-cyclohex-5-en-1-one inhibits Fas-mediated apoptosis by blocking self-activation of pro-caspase-8 in the death-inducing signaling complex (DISC). A series of ECH derivatives were asymmetrically synthesized via key synthetic intermediates obtained from lipase-catalyzed kinetic resolution. Inhibitory activities of the derivatives towards death receptor-mediated apoptosis both in type I and type 11 cells were investigated, revealing that novel non-peptide inhibitors, RKTS-33 and RKTS-34, are effective as ECH.
