alcohols, benzaldehydes, and DMSO to quinolines has been disclosed. For the reported annulation between 2-aminobenzyl alcohols and benzaldehydes, the change of the solvent from toluene to DMSO led to the change of the product from the diheteroatomic cyclic benzoxazines to monoheteroatomic cyclic quinolines. This annulation can be used to synthesize regioselectively different substituted quinolines
[3+1+1+1] Annulation to the Pyridine Structure in Quinoline Molecules Based on DMSO as a Nonadjacent Dual-Methine Synthon: Simple Synthesis of 3-Arylquinolines from Arylaldehydes, Arylamines, and DMSO
A [3+1+1+1] annulation of arylamines, arylaldehydes, and dimethyl sulfoxide (DMSO) to the pyridine structure in quinolines using DMSO as a nonadjacent dual-methine (═CH−) synthon is disclosed. In this annulation, arylamines provide two carbon atoms and one nitrogen atom, arylaldehydes furnish one carbon atom, and DMSO provides two nonadjacent methines (═CH−) to the pyridine ring in quinoline molecules
Compounds, compositions, and methods for modulating in vitro and in vivo processes mediated by selectin binding are described herein. For example, multimeric selectin modulators and their use are described, wherein the multimeric selectin modulators comprise a glycomimetic linked to a member of a class of compounds termed BASAs (Benzyl Amino Sulfonic Acids) or a member of a class of compounds termed BACAs (Benzyl Amino Carboxylic Acids).
