BIOMIMETIC SYNTHESIS OF BACTERIAL C50 CAROTENOIDS DECAPRENOXANTHIN AND C.p. 450

Alkylation of the distal double bond of pseudoionone 4 has been carried out with isoprene epoxide (ZnCl2/MeNO2) leading directly to α-cis 10a, α-trans 10b and γ 10c hydroxyprenylionones.The α-cis and γ-isomers have been converted in few steps into the C50 carotenoids decaprenoxanthin 1 and C.p. 450 3 respectively.
