The Sulfonamide Motif as a Synthetic Tool




Sulfonamides are well known motifs in medicinal chemistry, forming a large family of antibacterial agents as well as being found in numerous other drugs.  The chemistry of this functional group, however, is less well documented.  This review seeks to bring together the various applications and advantages of this motif in organic synthesis, which includes the sulfonamide as an activating group, protecting group, leaving group and as a molecular scaffold.

 The Sulfonamide Motif as a Synthetic Tool
Jonathan Wilden obtained his PhD from the University of Southampton in 2001 having worked on the total synthesis of the marine natural product pseudopterosin with Professor David Harrowven.  He then moved to the University of Sussex, Brighton, UK where his interest in sulfonamide chemistry began, working with Professor Steve Caddick.  In 2004 he was appointed lecturer at University College London where his research interests include the synthesis of medicinally important compounds and exploitation of the sulfonamide group in organic synthesis.

Boron vapour trail leads to heterofullerenes

A team of scientists has developed a simple way to synthesise heterofullerenes – fullerenes with atoms other than carbon in their structure – by exposing fullerenes to boron vapour during their growth. They found that atom exchange with a carbon takes place to form a derivative known as borafullerene. The team believes the process can be easily scaled up and applied to other all-carbon analogues including nanotubes or graphene.

Nickel-Catalyzed Suzuki–Miyaura Couplings in Green Solvents

Publication Date (Web): July 23, 2013 (Letter)
DOI: 10.1021/ol401727y

The nickel-catalyzed Suzuki–Miyaura coupling of aryl halides and phenol-derived substrates with aryl boronic acids using green solvents, such as 2-Me-THF and tert-amyl alcohol, is reported. This methodology employs the commercially available and air-stable precatalyst, NiCl2(PCy3)2, and gives biaryl products in synthetically useful to excellent yields. Using this protocol, bis(heterocyclic) frameworks can be assembled efficiently.
