Synthesis of functionalized carbamates and quinones via sequential oxidation of salicylaldehydes using TBHP as the oxidant
摘要:
A sequential oxidative approach was designed to functionalize salicylaldehyde derivatives and provide corresponding bi-functional amide-carbamate and amide-quinone units. A combination of metal/metal free conditions and TBHP as the external oxidant provided the products in moderate to excellent yields (49-91%). (C) 2014 Elsevier Ltd. All rights reserved.
Copper porphyrin-catalyzed construction of ether bond by cross-dehydrogenative coupling of sp [3] C–H bond with phenols bearing electron-withdrawing groups (EWG) was described for the first time. A broad range of substrates afforded different acetals in moderate to excellent yields with good functional group tolerance. The developed method is not only suitable for phenol substrates with ortho-directing

In certain aspects, the invention provides a method for treating a disease or condition in a subject, the method comprising co-administering to a subject in need thereof a therapeutically effective amount of at least one ULK1-inhibiting pyrimidine, and a therapeutically effective amount of an mTOR inhibitor.
The construction of C(sp<sup>3</sup>)–O bond via copper porphyrin catalyzed cross-dehydrogenative coupling reaction: Substituent and electronic effect of the catalysts
effect of copper porphyrin catalysts on the cross-dehydrogenativecoupling (CDC) reaction between the hydroxyl group of phenol substrates and C(sp3)-H bond have been investigated. Results showed that copper porphyrin bearing electron-withdrawing, bulky steric hindrance or heteroatom of pyridyl groups could increase the catalytic activity in the reaction. 5,10,15,20-(tetrakis(4-pyridyl)porphyrin)copper

construction of C(sp2)—Obond via coupling formamides with phenols was achieved firstly. A broad range of substrates afforded various carbamates in moderate to good yields with good functional group tolerance at low catalyst loading. Intermolecular competing kinetic isotope effect experiment indicated that the generation of formamide radical is the rate-determining step of current cross-dehydrogenative coupling
