Abstract
Microwave radiation is used as a heating source during the synthesis of heterocyclic compounds. The heating mechanisms involved in microwave-induced synthesis include dipolar polarization and ionic conduction. This heating technology follows the green protocol as it involves the use of recyclable organic solvents during synthesis. The microwave heating approach offers a faster rate of reaction, easier work-up procedure, and higher product yield with purity and also reduces environmental pollution. So, microwave heating is applied as a sustainable technology for the efficient production of pyrimidine compounds as one of the heterocyclic moieties. Pyrimidine is a six-membered nitrogenous heterocyclic compound that plays a significant role due to several therapeutic applications. This moiety acts as an essential building block for generating drug candidates with diverse biological activities, including anti-cancer (capecitabine), anti-thyroid (propylthiouracil), antihistaminic (pemirolast), antimalarial (pyrimethamine), antidiabetic (alloxan), antihypertensive (minoxidil), anti-inflammatory (octotiamine), antifungal (cyprodinil), antibacterial (sulfamethazine), etc. This review is focused on the synthesis of pyrimidine analogs under microwave irradiation technique and the study of their therapeutic potentials.

Abstract
trans-2-Amino-4-aryl-5-benzoyl-4,5-dihydrothiophene-3-carbonitriles were prepared either by the reaction of 3-aryl-2-cyanothioacrylamides with α-thiocyanatoacetophenone or by the Michael-type addition of cyanothioacetamide to α-bromochalcones followed by intramolecular cyclization. The mechanism of the first reaction was studied using high-level quantum chemical calculations. Density functional theory (DFT) studies were carried out to determine the mechanism of the first reaction. A new approach toward the construction of the thieno[2,3-d]pyrimidine core system was demonstrated by the reaction of the prepared dihydrothiophenes with HCHO and RNH2 under noncatalyzed Mannich conditions.

Abstract
Microwave Mediated Organic Synthesis (MMOS) is typical on the proficient heat
shift carried out by dielectric heating, which in turn, is primarily dependent on the capability
of the reagent or solvent to take up microwave energy. The employment of microwave energy
has witnessed a fast expansion in the past two decades, with novel and pioneering
applications in peptide and organic synthesis, material sciences, polymer chemistry, biochemical
processes and nanotechnology. This review summarizes current MW- mediated
catalytic reactions in use for the synthesis of a diversity of N-heterocycles by Multi-
Component Reactions (MCRs) and a variety of miscellaneous reactions. In addition, the
review addresses some aspects of the use of nanoparticles for a diversity of applications in
microwave chemistry.

Abstract
A series of eight polymethoxychalcone Mannich base derivatives 2a-2h was synthesized via
the microwave-assisted Mannich reaction of natural product 2'-hydroxy-3,4,4',5,6'-pentamethoxychalcone
(1) with various secondary amines and formaldehyde. Compared to conventional heating method
(80°C), the microwave-assisted method (700W, 65°C) is efficient with short reaction time (0.5-1 h) and
good yields (74-88%). The antiproliferative activities of eight Mannich base derivatives were evaluated
in vitro on a panel of three human cancer cell lines (Hela, HCC1954 and SK-OV-3) by CCK-8 assay.
The results showed that all of the Mannich base derivatives exhibited potential antiproliferative activities
on tested cancer cell lines with the IC50 values of 9.13-48.51 µM. Some active compounds exhibited
more activity as compared to positive control cis-Platin. Among them, compound 2b revealed to
have the strongest antiproliferative activity against all the three cancer cell lines with IC50 values ranging
from 9.13 to 11.24 µM.

Abstract
The development of novel heterocyclic compounds from simple and easily accessible starting components is of significant importance in medicinal chemistry. Due to the presence of active chromophores and potent pharmacological activities, nitroketene N,S-acetals have emerged as a fascinating building block in organic synthesis. The synergistic skeleton of these acetals and the presence of electron-donating as well as electron-withdrawing groups lead to the generation of distinctive structural features and are highly useful for building diverse heterocyclic rings. This review highlights the preparation of different nitroketene N,S-acetals and their applications in the synthesis of diverse heterocyclic compounds. This review highlights the synthesis of several kinds of nitroketene N,S-acetals and their applications in the synthesis of different kinds of heterocyclic compounds.![]()
