Heterocycles form, by far, the largest of the classical divisions of organic chemistry.
Moreover, they are of immense importance not only biologically and industrially but also to …

More than 100 years have passed since the first synthesis and structural recognition of
thioamides. Due to the great practical and synthetic applicability of that class of carboxylic …

Filling a gap on the market, this handbook and ready reference is unique in its discussion of
the usefulness of various heterocyclic systems in the synthesis of natural products. Clearly …

Cyclic peptides including cyclic depsipeptides are still a growing research area even in the
21st century. 1 They are mainly produced by marine organisms and terrestrial …

Heterocyclic compounds are of outstanding importance as pharmaceuticals, agrochemicals,
fine and bulk chemicals, and ligands for catalysis. 1 Among the different heterocycles, 2 …

A series of novel C2-symmetric bis (thiazoline) ligands with a diphenylamine backbone as a
linkage between two thiazoline rings were synthesized by the use of the simple reagent …

Microwave reactions of 2-amino-2-methyl-1-propanol (2) or 2-aminoethanethiol
hydrochloride (4) with readily available N-acylbenzotriazoles 1a− j in the presence of SOCl2 …

The isolation of the cytotoxic Lissoclinum sp. metabolite trunkamide A was reported in 1996.
After completion of a total synthesis in 1999, it became clear that the structure of this marine …

A combinatorial library of oxazolines and thiazolines was synthesized in moderate to
excellent yields using a newly developed methodology. Free carboxylic acids were directly …

The development of new strategies for synthesis of five-membered S-heterocycles has
remained a highly attractive but challenging proposition. An overview of the application of …
