Heterocycles | 2009

Metal-catalyzed heterocyclization: formation of five- and six-membered oxygen heterocycles through carbon-oxygen bond forming reactions

K. C. Majumdar; Pradip Debnath; B. Roy

This review describes the synthesis of five- and six-membered oxygen heterocycles through carbon-oxygen bond formation by metal catalyzed heterocyclization published during 2005 to 2008.


Journal of Sulfur Chemistry | 2008

Regioselective synthesis of indole-annulated sulfur heterocycles by tri-n-butyltin hydride-mediated aryl radical cyclization

K. C. Majumdar; Pradip Debnath; S. Alam; R. Islam

2-[(2-Bromobenzyl)sulfonyl]indoles under Bu3SnH-mediated aryl radical cyclization furnished exclusively the benzo[c]thiopyrano[2,3-b]indoles in 56–61% yields via 6-endo-trig cyclization whereas 2-[(2-bromobenzyl)sulfanyl]indole 3a gave only the β-scission product.
