Chromene is commonly found in nature and is considered one of the most frequently used
scaffolds in heterocyclic chemistry for the designing of chemical probes for therapeutic and …

Enantioselective organocatalysis has become a field of central importance within
asymmetric chemical synthesis and appears to be efficient approach toward the construction …

2 H-Chromenes (2 H-1-benzopyran derivatives) display a broad spectrum of biological
activities. The 2 H-chromene substructure is an important structural motif present in a variety …

Methods of synthesis and chemical properties of 3-nitro-$2 H $-chromenes, including
reactions with nucleophiles, cycloaddition, oxidation and reduction, have been reviewed …

Covering: 2010 and 2011. Previous review: Nat. Prod. Rep., 2010, 27, 1871 The chemistry
and biology of organic natural guanidines are reviewed, including the isolation, structure …

Nitro‐2H‐chromene and derivatives are the significant structural building blocks of many
natural products and pharmacologically active compounds. So, great deals of effort have …

A remarkably efficient three‐component reaction to synthesize 2‐amino‐4H‐chromenes
derivatives from malononitrile, various aromatic aldehydes, and orcinol was described at …

Pipecolic acids are cyclic non-protein amino acids serving as precursors for the biosynthesis
of biological metabolites. Structurally, the six-membered cyclic motif consists of five-carbons …

A new route to the chromene ring system has been developed which involves the reaction of
an α, β-unsaturated Fischer carbene complex of chromium with a propargyl ether bearing an …

A highly efficient and enantioselective intramolecular crossed Rauhut–Currier (RC) reaction
