The interest in synthesizing heterocycles has always been enormous. The literature contains
a variety of synthetic approaches to the heterocycle ring structures, much of which has been …

Heterocycles are an extraordinarily important class of compounds, making up more than half
of all known organic compounds. Heterocycles are present in a wide variety of drugs, most …

According to the CRC dictionary of natural products, 1 90% of chemically individual
molecules discovered in nature contain either a carbocyclic or a heterocyclic subunit. 2 Not …

Heterocyclic scaffolds represent the key structural subunits of many biologically active
compounds. Over the last few years iodine‐mediated reactions have been extensively …

In the past decades, an enormous number of reports have been dedicated towards the
synthesis of nitrogen containing heterocycles. This immense interest have emerged owing to …

The broad utility of cyclic structures accounts for the key roles that cycle-forming reactions
play in synthetic designs. Most of these reactions can be classified as either a cyclization of …

An efficient rhodium (III)-catalyzed redox-neutral C–H activation/cyclization/isomerization
strategy to prepare isoquinolines with complete regioselectivity from aromatic oxime esters …

Iodine has been recognized as an efficient, non-toxic, readily available and easy-to-handle
electrophilic reagent to favour halocyclization reactions for the synthesis of novel …

Nitrogen-containing heteroaromatic cores are ubiquitous building blocks in organic
chemistry. Herein, we present a family of metal-free intermolecular formal cycloaddition …

Herein, we report an efficient synthesis of azaspiro [4, 5]‐decanes and azaspiro [4, 5]‐
trienones by the radical cascade spirocyclization of N‐benzylacrylamides or N …
