Abstract 140 Years ago Adolf von Baeyer proposed the structure of a heteroaromatic
compound which revolutionized organic and medical chemistry: indole. After more than a …

The assembly of architecturally complex alkaloids embedding the indole nucleus is of
paramount importance for the target oriented synthesis of biologically active molecules. 1 A …

Abstract Vor 140 Jahren schlug Adolf von Baeyer die Struktur für eine heteroaromatische
Verbindung vor, die die organische und medizinische Chemie nachhaltig veränderte: Indol …

Whereas the beneficial effect of water on reaction rate is decreased with an increase of the
reactant′ s hydrophobicity, we report here that the use of glycerol as solvent was able to …

As a continuation of our efforts directed towards the development of anti-diabetic agents
from natural sources, piplartine was isolated from Piper chaba, and was found to inhibit …

Sulfamic acid-catalyzed Michael addition of indoles and pyrrole to electron-deficient nitroolefins
under solvent-free condition - ScienceDirect Skip to main contentSkip to article Elsevier logo …

The Michael reaction is a widely used reaction for the C–C coupling of electron-poor olefins
and C (sp3)–H pronucleophiles. Herein we report the Michael reaction between alkenes …

A neutral catalytic system for Michael reactions of indoles has been developed by combining
silica-supported benzenesulfonic acid sodium salt with hydrophobic ionic liquid in water. An …

We report a base-promoted metal-free approach for the synthesis of thieno [2, 3-b] indole
derivatives. This method combined four C–H σ-bond cleavage reactions of two different …

An effective and clean FC alkylation of indoles and electron-rich arenes with β-nitroalkenes
in HFIP was reported. The desired products are formed rapidly in excellent yields under mild …
