Mal, Sajal K.,Bohé, Luis,Achab, Sa?d
, p. 5904 - 5914 (2008/12/20)
Topsentins and related bis-indole alkaloids may be efficiently synthesized through an addition/oxidation sequence leading to 2-(3-indolylcarbonyl)-imidazole derivatives followed by a Pd-catalyzed heteroarylation with the appropriate 3-stannylindoles.
A three-component coupling approach to the marine bis-indole alkaloids: Topsentin, deoxytopsentin and bromotopsentin
Achab, Said
, p. 5503 - 5506 (2007/10/03)
The total syntheses of three marine bis-indole alkaloids (1, 2, 4) of the topsentin family together with the synthesis of unnatural deoxybromotopsentin (33) are described. Key elements include, a 1,2-addition-oxidation sequence to construct the bis-hetero
