L. Schio et al., Tosylates in palladium-catalysed coupling reactions. Application to the synthesis of arylcoumarin inhibitors of gyrase B, TETRAHEDR L, 41(10), 2000, pp. 1543-1547
The palladium-catalysed coupling reaction between tosylate derivatives and
organostannanes has been investigated as a methodology for carbon-carbon bo
nd formation. Aryl substituents have been successfully incorporated even in
highly functionalised coumarin structures to afford new analogues of the a
ntibiotic novobiocin. (C) 2000 Elsevier Science Ltd. All rights reserved.
