Efficient one-pot synthesis of anti HIV and antitumor compounds: harman and substituted harmans
摘要:
Anti HIV and antitumor compounds, harman and substituted harmans have been synthesized using electrocyclization reactions as key steps. A one-pot reaction sequence was used to furnish these compounds in good overall yield. (C) 2003 Elsevier Science Ltd. All rights reserved.

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-beta-carbolines. A one-pot reaction sequence was used to furnish these compounds in good yield. (C) 2004 Elsevier Ltd. All rights reserved.

described. The key step, formation of the 1-phenylacetyl β- carboline, involves a tandem aza Wittig / electrocyclicringclosure process. The first synthesis of the alkaloid xestomanzamine A is achieved by coupling of a N-protected harmane, now available via aza Wittig / electrocyclicringclosure process, with a 5-lithioimidazole derivative.
