Special Issue Information

Dear Colleagues,

Development of environmentally benign reactions has been the subject of intense current investigation. Toward the goal catalytic reactions with non-toxic reagents has been identified as one of the best procedures in organic synthesis. Currently, a large number of organic reactions have been studied using bismuth salts. As a result, many new compounds have been synthesized using different types of bismuth salts. Notably, most of the bismuth salts are inexpensive Lewis acid, non-toxic, and readily available reagents. In view of the rapidly expanding field of bismuth salts-mediated reactions and significant attention in this area from academic and industrial scientists, an issue of a journal on organobismuth mediated reactions would be necessary and timely. Molecules has selected this subject as a part of their endeavor to uncover new and useful reactions to the scientists working on organobismuth chemistry. The principal goal of this issue will be to provide pertinent information to researchers who are interested in the chemistry of organobismuth reagents and their fascinating role in organic synthesis. Synthesis of important organic compounds under environmentally benign conditions will also be explored. Efforts will be made to understand the mechanism of bismuth salts-mediated reactions in different solvents including in water.

Abstract
Starting from benzofuran-2-methanal, 6-substituted benzothiazole-2-amines and malonic esters, sixteen title compounds were designed and synthesized seeking to introduce anti-TMV activity. The structures of the newly synthesized compounds were confirmed by 1H-NMR, 13C-NMR, IR spectra, and MS (HREI) analysis. The bioassays [...] Read more.
Starting from benzofuran-2-methanal, 6-substituted benzothiazole-2-amines and malonic esters, sixteen title compounds were designed and synthesized seeking to introduce anti-TMV activity. The structures of the newly synthesized compounds were confirmed by 1H-NMR, 13C-NMR, IR spectra, and MS (HREI) analysis. The bioassays identified some of these new compounds as having moderate to good anti-TMV activity. The compounds 5i and 5m have good antiviral activity against TMV with a curative rate of 52.23% and 54.41%, respectively, at a concentration of 0.5 mg/mL. Full article

Open AccessArticle A Highly Efficient Bismuth Salts-Catalyzed Route for the Synthesis of α-Aminophosphonates
Molecules 2010, 15(11), 8205-8213; doi:10.3390/molecules15118205

Abstract A convenient synthesis of different types of α-amino phosphonates via one-pot solvent-free three component reactions of aldehydes, amines and phosphites catalyzed by bismuth salts has been investigated. Bismuth triflate is found to be the most effective catalyst for this reaction. Full article

Abstract
Steroid and terpene chemistry still have a great impact on medicinal chemistry. Therefore, the development of new reactions or “greener” processes in this field is a contemporaneous issue.

Steroid and terpene chemistry still have a great impact on medicinal chemistry. Therefore, the development of new reactions or “greener” processes in this field is a contemporaneous issue. In this review, the use of bismuth(III) salts, as “ecofriendly” reagents/catalysts, on new chemical processes involving steroids and terpenes as substrates will be focused. Special attention will be given to some mechanistic considerations concerning selected reactions. Full article
