Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12 - 18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.

The journal will publish rapid, short, communications, full, detailed articles, and shorter, less developed notes. Periodically, the editors will solicit reviews on the latest main group developments. In particular, we would like to eventually publish reviews covering every column of the main group elements, and some that are focused on single elements. This will advertise and showcase the beauty and breadth of main group chemistry.

Conventional- and microwave-induced synthesis of biologically active 1,4-dihydropyridine derivatives containing benzothiazolyl moiety

Authors: Mithlesh, | Pareek, Pawan K. | Kant, Ravi | Ojha, Krishan G.

Article Type: Research Article

Abstract: A series of N-(6-methoxybenzothiazolyl)-2,3,5,6-tetrasubstituted-4-(aryl)-1,4-dihydropyridines was synthesized by reaction of 2-amino-6-methoxybenzothiazole, aromatic aldehyde and active methylene compound in methanol by conventional as well as microwave irradiation (solvent free and solid support) methods. The microwave irradiation technique gives better yield and the reaction is complete in a very short period of time. Under microwave irradiation better yields are obtained in acidic alumina as compared to silica, neutral alumina, and basic alumina. All compounds were tested for antibacterial and antifungal activities and the results were compared with standard drugs. Entomological activities were also tested. The results showed that a change in substitution pattern … Show more

Synthesis and biological evaluation of 3-[p-(heterocyclocarbonyl)]phenylsydnones from the versatile precursor, 3-[p-(hydrazinocarbonyl)]phenylsydnone

Authors: Jogul, Johnson J. | Phaniband, Mohammedshafi A. | Pattan, S.R. | Badami, B.V.

Article Type: Research Article

Abstract: The synthetic versatility of 3-[p-(hydrazinocarbonyl)]phenylsydnone is demonstrated in the syntheses of various heterocyclic compounds. For example, pyrazoles, fused pyranopyrazoles, 1,3,4-thiadiazoles, 1,3,4-oxadiazoles and 1,2,4-triazoles can be built on the phenyl ring of this 3-phenyl sydnone. The phenylsydnones prepared herein were characterized spectroscopically and subjected to antibacterial and antifungal screening. The compounds demonstrated high fungicidal activities. 3-[p-(hydrazinocarbonyl)]phenylsydnone has proven to be a versatile precursor for the synthesis of various related derivatives and may be used further in preparing various pharmaceutical and agricultural compounds.
