  Gold-Catalyzed Cycloisomerization of 1,6-Diyne Carbonates and Esters to 2,4a-Dihydro-1H-fluorenes

  摘要：

  A synthetic method to prepare 2,4a-dihydro-1H-fluorenes efficiently from gold(I)-catalyzed 1,2-acyloxy migration/cyclopropenation/Nazarov cyclization of 1,6-diyne carbonates and esters is described. The suggested reaction pathway provides rare examples of [2,3]-sigmatropic rearrangement in this class of compounds as well as the involvement of an in situ formed cyclopropene intermediate in gold catalysis. Experimental and ONIOM(QM:QM') [our own n-layered integrated molecular orbital and molecular mechanics(quantum mechanics quantum mechanics')] computational studies based on the proposed Au carbenoid species provide insight into this unique selectivity.

  functionalization of acyl heterocycles through a hydrogen‐atom transfer (HAT) process and the use of tailor‐made ketimines as reliable electrophilic partners. This transformation is translated into an enantiomerically controlled radical/polar cascade reaction in which water is produced as the sole by‐product and stereoselectivity is dictated by coordination to a chiral‐at‐rhodium catalyst.

  在此，介绍了一种光驱动、原子经济的过程，该过程提供了获得对映体富集的取代手性 1-吡咯啉衍生物的途径。该策略涉及通过氢原子转移（HAT）过程对酰基杂环进行远端官能化，并使用定制的酮亚胺作为可靠的亲电伙伴。这种转变转化为对映体控制的自由基/极性级联反应，其中产生的唯一副产物是水，立体选择性取决于与铑手性催化剂的配位。

  Estrogen-related receptor gamma (ERRγ) has recently been recognized as an attractive target for treating inflammation, cancer, and metabolic disorders. Herein, we discovered and demonstrated the in vitro pharmacology as well as the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties of chemical entities that could act as highly selective inverse agonists for ERRγ. The results were comparable to those for GSK5182 (4), a leading ERRγ inverse agonist ligand. Briefly, the half-maximal inhibitory concentration (IC50) range of the synthesized compounds for ERRγ was 0.1-10 μM. Impressively, compound 24e exhibited potency comparable to 4 but was more selective for ERRγ over three other subtypes: ERRα, ERRβ, and estrogen receptor α. Furthermore, compound 24e exhibited a superior in vitro ADMET profile compared to the other compounds. Thus, the newly synthesized class of ERRγ inverse agonists could be lead candidates for developing clinical therapies for ERRγ-related disorders.

  A novel and efficient procedure for the synthesis of δ,γ-alkynyl esters by the conjugate addition of alkynylsilanes to acrylate esters in the presence of a catalytic amount of indium(III) chloride has been developed. This method provides a rapid and efficient access to substituted δ,γ-alkynyl esters.
