Carbazole 1 was isolated first from coal tar in 1872 by Graebe and Glazer (Figure 1). 1 In
1965, Chakraborty et al. described the isolation and antibiotic properties of murrayanine …

Abstract The hetero Diels-Alder reaction is one of the most important methods for the
synthesis of heterocycles. In this article an overview is given for the period since 1989 …

An efficient Rh (III)-catalyzed synthetic method for indoloquinoline derivatives from readily
available indoles and isoxazoles was developed. This annulation procedure undergoes …

Four methodologies based on the aza-Wittig reaction have been used for the preparation of
the wide variety of nitrogen-containing natural products. The synthesis of quinoline, β …

A direct one-pot approach to the synthesis of carbazoles (mono-, di-, and trisubstituted) and
α-carbolines from readily available indoles or 7-azaindoles and alkenes is described. Based …

Tandem radical cyclizations of suitably substituted N-aryl thiocarbamates, thioamides, and
thioureas are induced by exposure to tris (trimethylsilyl) silane (TTMSH) and UV light and …

Within the last decades, the aza-Wittig reaction has assumed increasing importance for the
specific construction of many heterocyclic systems. This first comprehensive review provides …

2-Allylphenols react with carbon monoxide and hydrogen in the presence of catalytic
quantities of a cationic palladium (II) complex [(PCy3) 2Pd (H)(H2O)]+ BF4-or palladium …

A facile, metal-free method for the synthesis of substituted α-carbolines from secondary
Morita–Baylis–Hillman (MBH) acetates of nitroalkenes is presented. The cascade reaction of …
