Abstract :
A convergent synthesis provided a C25 and a C35 oxidopolyprene in which a farnesyl C15 unit is connected in a head-to-head fashion to a geranyl C10 or a geranylgeranyl C20 unit. When incubated with recombinant β-amyrin synthase from Pisum sativum the C25 oxidopolyprene was enzymatically converted to an unnatural novel tetracyclic sesterterpene, while the C35 analogue did not afford any cyclization product.
