A radical cyclisation based strategy to cuparenoids; synthesis of (+)-α-cuparenone, (+)-epilaurene and laurenes

Mercuric acetate catalysed one pot Claisen rearrangement of the cinnamyl alcohol 5, generated the pent-4-enal 9, which on homologation resulted the hex-5-enal 10. Radical cyclisation of the radical anion derived from 10, followed by oxidation provided the

Synthesis of α-Cuparenone

Ethyl 2-carbethoxy-3-p-tolylpropanoate (VII) on Michael reaction with acrolein followed by acetal formation furnishes acetal-malonate (IX).The diacid (X), obtained by hydrolysis of IX, is warmed with lead tetraacetate-pyridine mixture, and the resulting p
