Catalysis research under bromine is a well-known topic in organic synthesis. However, hazardous and toxic nature of bromine and its negative and deleterious effects on the human health has caused organic chemists to avoid working on bromine. Although, in the last decade, a category of heterogeneous bromine source catalysts (especially N-tribromides) has been introduced to overcome this problem, nevertheless, the re Read More

Polyhydroxyalkanoates (PHAs) and other biopolymers vary in their behavior and properties, but are extremely useful in medical applications because of their biodegradability. As long-term problems arise with permanent implants, different biopolymers can be selected and blended to replace the old PHAs and other homopolymers with new, less invasive alternatives. Scaffolds and surgical meshes are not designed to fu Read More

Naratriptan 1 is a selective serotonin 5-hydroxytryptamine 5-HT1 receptor subtype agonist used for the treatment of acute attacks of migraine headaches and for cluster headaches. Since its discovery in 1998 by GlaxoSmithKline, a number of synthetic methods have been reported up till now. This review aims to focus soberly the various synthetic key routes used for the synthesis of naratriptan 1 in high yields. An effort ha Read More

Template polymerization refers to the synthesis of cationic polyacrylamide (CPAM) with microblock structures. The definition of template polymerization and the reaction mechanism of synthesizing CPAM are presented in this paper. The selection of a template for template polymerization is discussed along with the related kinetic problems and the sequence structure of CPAM that is synthesized via template Read More

Background: It is known that squaramides are able to form up to four hydrogen bonds, in which the remarkably rigid four-membered ring system serves as an ideal hydrogen bond donor/ acceptor unit. Because of the unique physical and chemical properties of squaramides, design and synthesis of squaramide-based functional receptors have become a hot topic in recent years. Objective: This paper reviews the recent a Read More

A generally accepted classification distinguishes semiconductor photocatalysis in type A and type B. The first class comprehends reactions where the primary redox products (radical anions and cations) further evolve giving rise to the final reduced and oxidized species. Type B reactions occur when the primary redox products undergo intermolecular bond formation to addition products. Recently, some photocatalytic reactions Read More
