Direct Use of Unprotected Aliphatic Amines to Generate N-Heterocycles via β-C–H Malonylation with Iodonium Ylide
摘要:
An unprecedented method that enables the direct transformation of unprotected secondary aliphatic amines into functionalized N-heterocycles in the absence of transition metals was developed. The activation of these NH-free amines by the iodonium ylide induces a site-selective beta-C-H malonylation process, allowing the construction of three sigma-bonds and one pi-bond in a simple operation.
Heterocyclic compounds of Formula (I) shown herein. Also disclosed are pharmaceutical compositions containing the heterocyclic compounds and methods of using the heterocyclic compounds to mobilize hematopoietic stem cells and endothelial progenitor cells into the peripheral circulation. Further provided are methods for treating tissue injury, cancer, inflammatory disease, and autoimmune disease with the heterocyclic compounds.

Substituted biaryl piperazinyl-pyridine analogues are provided, of the Formula:
wherein variables are as described herein. Such compounds are ligands that may be used to modulate specific receptor activity in vivo or in vitro, and are particularly useful in the treatment of conditions associated with pathological receptor activation in humans, domesticated companion animals and livestock animals. Pharmaceutical compositions and methods for using such compounds to treat such disorders are provided, as are methods for using such ligands for receptor localization studies.
The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
