Abstract:
Background: 1,4-Dithiane-2,5-diol (1,4-DTD) is the stable dimer of α-mercapto acetaldehyde. This commercially available ambidentade compound is characterized as having in its chemical structure one group that acts as an electrophile and another that acts as a nucleophile, this permits its use as versatile and efficient synthon in synthetic heterocycle procedures. Objective: The aim of this review is to present synthetic applications of 1,4-DTD in heterocyclic chemistry and their applicability to the synthesis of bioactive compounds.

Abstract:
Department of Chemistry, University of Rajasthan, Jaipur-302 004 In recent decades, there has been considerable interest in medical applications and biochemistry of organic compounds containing fluorine. The discovery of 5-fluoronracil in the fifties is a classical example of a heterocyclic compound where the replacement of even one hydrogen by a fluorine atom led to great modification in biological activity of the parent non-fluorinated heterocycle. This presentation gives a background to this exciting new area in organic chemistry and briefly describes some of the recent work in the author&#

Abstract:
The utilization of green chemistry techniques is dramatically reducing chemical waste and reaction times as has recently been proven in several organic syntheses and chemical transformations. To illustrate these advantages in the synthesis of bioactive heterocycles, we have studied various environmentally benign protocols that involve greener alternatives. Microwave (MW) irradiation of neat reactants catalyzed by the surfaces of recyclable mineral supports, such as alumina, silica, clay, or their "doped" versions, enables the rapid one-pot assembly of heterocyclic compounds, such as flavonoids
