Synthesis of pulvinic acid and norbadione A analogues by Suzuki-Miyaura cross-coupling of benzylated intermediates

Murr, Marine Desage-El,Nowaczyk, Stephanie,Le Gall, Thierry,Mioskowski, Charles

, p. 1489 - 1498 (2007/10/03)

Pulvinic acid and norbadione A analogues can be prepared by Suzuki-Miyaura cross-coupling of functionalized aryl-boronic esters with appropriate vinyl inflates, in which the hydroxy functions are protected either with methyl or benzyl groups, the latter being cleaved in a more reliable fashion at the end of the synthetic sequence.
