2,3-Disubstituted pyrrolo[2,3-b]pyridines were synthesized by palladium-catalyzed heteroannulation of 2-amino-3-iodopyridine derivatives and internal alkynes with Pd(OAc)2, LiCl, and KOAc in DMF. The 2-trimethylsilyl-3-methylpyrrolo[2,3-b]pyridine was transformed to 2-substituted-3-methylpyrrolo[2,3-b]pyridines.
2,3-二取代的吡咯并[2,3- b ]吡啶是通过钯催化的2-氨基-3-碘吡啶衍生物和内部炔烃与Pd(OAc)2,LiCl和KOAc在DMF中的杂环化反应合成的。将2-三甲基甲硅烷基-3-甲基吡咯并[2,3- b ]吡啶转化为2-取代的-3-甲基吡咯并[2,3- b ]吡啶。

Fluorescent base analogues comprise a group of increasingly important molecules for the investigation of nucleic acid structure, dynamics, and interactions with other molecules. Herein, we report on the quantum chemical calculation aided design, synthesis, and characterization of four new putative quadracyclicadenineanalogues. The compounds were efficiently synthesized from a common intermediate

Syntheses and structure activity relationships (SA R) of nonsteroidal glucocorticoid receptor (GR) agonists are described. These compounds contain azaindole moieties as A-ring mimetics and display various degrees of in vitro dissociation between gene transrepression and transactivation. Collagen induced arthritis studies in mouse have demonstrated that in vitro dissociated compounds (R)-16 and (R)-37 have steroid-like anti-inflammatory properties with improved metabolic side effect profiles, such as a reduced increase in body fat and scrum insulin levels, compared to steroids.

A series of 2-substituted 5-, 6- and 7-azaindoles were synthesized from iodo-N-(tert-butoxycarbonyl)aminopyridines via the corresponding allenyl derivatives.
A General and Efficient Synthesis of Azaindoles and Diazaindoles
The DBU-mediated cyclization of ortho-(Boc-amino)alkynyl pyridines. -pyridazines, -pyrimidines and -pyrazines efficiently generates azaindoles and diazaindoles, respectively. The reaction proceeds under mild conditions and in high yields. A variety of functional groups are tolerated.
