Abstract
Single-atom catalysts (SACs) have generated excitement for their potential to downsize metal particles to the atomic limit with engineerable local environments and improved catalytic reactivities and selectivities. However, successes have been limited to small-molecule transformations with little progress toward targeting complex-building reactions, such as metal-catalyzed cross-coupling. Using a supercritical carbon-dioxide-assisted protocol, we report a heterogeneous single-atom Pt-catalyzed Heck reaction, which provides the first C-C bond-forming migratory insertion on SACs. Our quantum mechanical computations establish the reaction mechanism to involve a novel C-rich coordination site (i.e., PtC4) that demonstrates an unexpected base effect. Notably, the base was found to transiently modulate the coordination environment to allow migratory insertion into an M-C species, a process with a high steric impediment with no previous example on SACs. The studies showcase how SACs can introduce coordination structures that have remained underexplored in catalyst design. These findings offer immense potential for transferring the vast and highly versatile reaction manifold of migratory-insertion-based bond-forming protocols to heterogeneous SACs.

Abstract
Herein we present an investigation into the scope and mechanism for the synthesis of cyclopentyl and heterocyclic fused pyridones from the corresponding enyne amides. In the presence of a secondary amine, cyclization proceeds smoothly to form 5,6-bicyclic pyridones in 12-90% yield. The cyclization fails with enyne amides of six-membered and larger ring systems. The ring closure reaction is catalytic in nature with respect to the secondary amine and proceeds via sequential 1,6-addition of the amine, 6-exo-trig ring closure of the iminium intermediate, and subsequent elimination of the secondary amine. Computations show reduced conjugation between the enyne and amide for six-membered and larger systems, thereby providing an explanation for the inability of such enyne amides to form fused pyridones.

Abstract
INTRODUCTION FGFR1 is a well known molecular target for anticancer therapy. Many studies have proved that the regulation of FGFR1 activity is a promising therapeutic approach to treat a series of cancers. Therefore, the development of potent inhibitors has consequently become a key focus in the present drug discovery, and it is encouraging that several highly selective FGFR1 inhibitors have been identified from various sources in recent years. Areas covered: This article reviews patents and patent applications related to selective FGFR1 inhibitors published from 2010 to 2016. This summary highlights about 15 patents from different pharmaceutical companies and academic research groups. We used Baidu and NCBI search engines to find relevant patents as a search term. Expert opinion: In the past few years, considerable progress has been made in the identification and development of selective FGFR1 inhibitors in use. At present, at least 10 inhibitors of FGFR1 are in clinical trials, and several agents have shown encouraging results under experimental conditions. Given the fact that FGFR1 plays a crucial role in the regulation of cancer and other diseases, we hope that it will gain further attraction from pharmaceutical companies and encourage development of more novel, safe and efficient FGFR1 inhibitors in the future.
