DOI: 10.1016/j.mencom.2019.11.028

Abstract: 1-(2-Aminoethylsulfonyl)-2-phosphorylpyrrolidines have been synthesized via boron trifluoride-catalyzed Arbuzov reaction of 2-ethoxy-1-(vinylsulfonyl)pyrrolidine with triethyl phosphite followed by aza-Michael reaction of thus obtained 2-phosphoryl-1-(vinylsulfonyl)pyrrolidine with secondary amines. The cytotoxicity of the prepared 1-(2-aminoethylsulfonyl)-2-phosphorylpyrrolidines against M-Hela tumor cell… read more here.

DOI: 10.1021/jacs.1c04835

Abstract: We present a modular, synthetic entry to polysubstituted pyrroles employing readily available 2,5-dihydrothiophenes. Ring-opening of the heterocycle provides access to a panel of 1,3-dienes which undergo pyrrole formation in the presence of inexpensive chloramine-T trihydrate.… read more here.

DOI: 10.1039/d2cc01986h

Abstract: peri-Substituted naphthalene complexes (Trip2Pn)2Naph (Pn = Sb 1, Bi 2) were synthesised and their redox behaviour investigated. Oxidation of 1 with [Fc][BArF] (BArF = B(C6F5)4) yielded [(Trip2Sb)(TripSb)Naph][BArF] (3) containing the stibane-coordinated stibenium cation [(Trip2Sb)(TripSb)Naph]+. Subsequent… read more here.
