Cu(OAc)2-CatalyzedN-Arylation of Sulfonamides with Arylboronic Acids or Trimethoxy(phenyl)silane
摘要:
Cu(OAc)2-catalyzed C-N bond-formation reaction of sulfonamides with organoboronic acids or trimethoxy(phenyl)silane was achieved in the presence of 20mol% of Cu(OAc)2, providing N-arylation products with yields ranging from moderate to good.
Bissulfonamide derivatives of formula (I) are capable of inhibiting: a) the biosynthesis of aromatic amino acids via the shikimate pathway and b) the catabolism of quinic acid, wherein: Ar is an aryl or heteroaryl group; R1 and R2 are the same or different and each represent hydrogen or alkyl or R1 and R2 together form a C1-C3 alkylene group, -CO- or -CS-; and R3 and R4 are the same or different and each represent -alkyl-aryl, -alkyl-heteroaryl, -alkenyl-aryl, -alkenyl-heteroaryl, -alkynyl-aryl-alkynyl-heterorayl, aryl or heteroaryl.
