Total synthesis of two naturally occurring bicyclo[3.2.1]octanoid neolignans.
The first total syntheses of the racemates of naturally occurring macrophyllin-type bicyclo[3.2.1]octanoid neolignans, kadsurenin C 3 and kadsurenin L 4, were accomplished starting from vanillin and resorcinol. The acid-catalyzed rearrangement of hydrobenzofuranoid neolignans into bicyclo[3.2.1]octanoid neolignans was used as the key step.
