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

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.

Dioxolanones as Synthetic Intermediates. Part 4. Biomimetic Synthesis of Multicolanic Acid

Regiospecific cyclisation of the intermediate formed by reaction of the dioxolanone (9) with methyl α-lithioheptanoate gave (Z)-t-butyl multicolanate (13) in 53percent yield.Photochemical stereomutation of (13) gave (E)-t-butyl multicolanate (16) which was converted by trifluoroacetic acid into (E)-multicolanic acid (3), a metabolite of P. multicolor.In the same way, reaction of (9) with methyl α-lithiophenylacetate and, if desired, subsequent photochemical irradiation, provided (Z)- and (E)-4-carboxymethylene-2-phenyltetronic acids (21) and (23).
