Synthesis of Phosphorus and Sulfur Heterocycles via Ring-Closing Olefin Metathesis

Crystal structure of 2,4,5-tribromo-1-methyl-1H-imidazole, C4H3Br3N2

“…The imidazole core is akey for ahuge variety of important biologically active substances. It has found many applications in metalcarbene catalysts and is most important in ionic liquids (ILs) and magnetic ILs [3][4][5][6][7][8]. Polybrominated imidazole building blocks are useful as starting materials in the synthesis of very dense halogenated ILs [9].…”

Nucleoside substituted perhydro-1λ5-[1,3,2]diazaphospholo[1,5-a]pyridine-1-thione analogues: Synthesis and evaluation of antiviral and antimicrobial activities

“…[1][2][3] In particular, phosphorus heterocyclic compounds with five and six membered consisting of heteroatoms like nitrogen and oxygen have been attained significant interest due to their important applications in organic synthesis 3 and large varieties of biological activities such as herbicidal, 4,5 insecticidal 6 and antimicrobial. 7 Further, the phosphorous compounds with P-N functionality like diazaphospholes have been attained great interest due to their significant medicinal, pesticidal, [8][9][10][11] antiviral, bactericidal, antioxidant, 12 and anti-carcinogenic activities.…”

Synthesis of Thioethers by InI3-Catalyzed Substitution of Siloxy Group Using Thiosilanes

“…Organosulfur compounds are important building blocks in organic synthesis because many natural and pharmaceutical products contain sulfur [1][2][3][4][5]. In particular, a thioether is a popular and useful compound [1][2][3][4][5].…”

“…In particular, a thioether is a popular and useful compound [1][2][3][4][5]. Therefore, there are various types of synthetic methods to produce thioethers such as hydrothiolation of alkenes [6][7][8][9], Chan-Lam-Evans coupling using thiols [10], and transition metal-catalyzed coupling between aryl halides and thiols [11,12].…”
