View page
US Patent:
20050255575, Nov 17, 2005
Filed:
Apr 27, 2005
Appl. No.:
11/115502
Inventors:
Dhandapani Venkataraman - Hadley MA, US
Craig Bates - Pelham NH, US
Pranorm Saejueng - Amherst MA, US
International Classification:
C12N009/00
US Classification:
435183000
Abstract:

US Patent:
7473786, Jan 6, 2009
Filed:
Dec 6, 2004
Appl. No.:
11/005365
Inventors:
Dhandapani Venkataraman - Hadley MA, US
Craig G. Bates - Pelham NH, US
Pranorm Saejueng - Amherst MA, US
Assignee:
University of Massachusetts - Boston MA
International Classification:
C07D 209/10
C07D 307/79
US Classification:
548490, 549469
Abstract:
A copper(I)-catalyzed procedure for the synthesis of benzo[b]heterocycles. This protocol can be used to synthesize a variety of 2-arylbenzo[b]furans and indoles in good to excellent yields. This method can tolerate a variety of functional groups, does not require the use of expensive additives and is palladium-free.
