The invention provides tetrahydroquinoline sulfonamide compounds, tetrahydronaphthalene sulfonyl compounds, and related compounds, pharmaceutical compositions, methods of promoting RORy activity, methods of increasing the amount of IL-17 in a subject, and methods of treating cancer and other medical disorders using such compounds.
Na-exchanged X type zeolite, commercially available as MS-13X, effectively catalyzes thiol-disulfane exchange reactions under aerobic mild conditions to give the unsymmetrical disulfanes in good-to-high yields. Various thiols and disulfanes are tolerant in the catalytic systems. Preliminary mechanistic studies suggest the involvement of base-catalyzed SN2-S displacement and/or addition-elimination mechanisms
Na 交换的 X 型沸石,作为 MS-13X 可商购,在有氧温和条件下有效催化硫醇 - 二硫烷交换反应,以良好到高的产率得到不对称二硫烷。在催化系统中可以耐受各种硫醇和二硫烷。初步的机理研究表明,碱催化的 S N 2-S 置换和/或加成消除机制参与了氢键相互作用。
