The invention features compounds, pharmaceutical compositions and methods for treating patients who have an EGFR-driven cancer of Formula (I), wherein the variables are as defined herein.
An unprecedented boron-containing fluorophore, π-extended cis-stilbene, obtained via alkynylboration reaction of alkynamide is reported. Boron-containing π-extended cis-stilbenes emit fluorescence with high quantum yields in the solid state and exhibit aggregation-induced emission enhancement. The broad substrate scope of the alkynylboration reaction offers facile access to electronically diverse structures

A very mild protocol for fixation of carbon dioxide with 2-alkynamides in DMSO at 30 °C using a CO2 balloon in the presence of K2CO3 has been developed, which leads to an efficient assembly of oxazolidine-2,4-diones. It is observed that the regioselectivity was controlled by the aryl group.

We report a transition-metal-free trans-selective semireduction of alkynes with pinacolborane and catalytic potassium tert-butoxide. A variety of 3-substituted primary and secondary propiolamides, including an analog of FK866, a potent nicotinamide mononucleotide adenyltransferase (NMNAT) inhibitor, are reduced to the corresponding (E)-3-substituted acrylamide derivatives in up to 99% yield with >99:1
我们报道了频哪醇硼烷和催化叔丁醇钾对炔烃的无过渡金属反式选择性半还原。各种 3-取代的一级和二级丙炔酰胺,包括 FK866 的类似物(一种有效的烟酰胺单核苷酸腺苷酸转移酶 (NMNAT) 抑制剂),可被还原为相应的 ( E )-3-取代的丙烯酰胺衍生物,产率高达 99%,且 >99 :1 E / Z选择性。机理研究表明,活化的路易斯酸碱配合物将氢化物转移到α-碳上,然后以反式方式快速质子化。

A base-mediated trans-hydroboration of propiolamides that provides access to previously elusive primary and secondary (E)-β-borylacrylamide products has been developed. In the presence of n-butyllithium and pinacolborane, complete regioselectivity and stereoselectivity is observed, affording the corresponding vinylboronate products in up to 91% yield. A wide variety of primary and secondary amides
