Use of Conjugated Dienones in Cyclialkylations: Total Syntheses of Arucadiol, 1,2-Didehydromiltirone, (±)-Hinokione, (±)-Nimbidiol, Sageone, and Miltirone
摘要:
Functionalized hydrophenanthrenes can be prepared using a cyclialkylation-based strategy. These annulations are highly dependent on the directing effects of the arene substitutents and on conformational considerations. The utility of this methodology was featured in the syntheses of six diterpenoids.

Dioxocyclohexane carboxylic acid phenyl amide derivatives of Formula (I) or a tautomer or a pharmaceutically acceptable salt thereof or both, and pharmaceutical compositions containing the same are provided:
The dioxocyclohexane carboxylic acid phenyl amide derivatives are useful for treating a variety of conditions associated with the abnormal modulation of one or more Kv1.1 voltage-gated potassium channels.

Catalytic Allylic Oxidation to Generate Vinylogous Acyl Sulfonates from Vinyl Sulfonates
作者:James K. Tucker、Matthew D. Shair

日期:2019.4.5
formation of vinylogous acyl sulfonates was accomplished via the allylic oxidation of the corresponding vinyl sulfonates. The reaction progressed through the agency of catalytic iron(III) chloride catalysis with tert-Butyl hydroperoxide (TBHP) as the stoichiometric oxidant. Tolerance of other functional groups, including some other allylic and benzylic sites, was observed.
