Efficient one-pot synthesis of anti-HIV and anti-tumour β-carbolines
Kusurkar, Radhika S.,Goswami, Shailesh K.
, p. 5315 - 5318 (2004)
Thermal electrocyclisation of the azahexatriene system has been used as a key step for the synthesis of anti-HIV and anti-tumour compounds, harman, derivatives of harman and 1-aryl-β-carbolines. A one-pot reaction sequence was used to furnish these compounds in good yield.
