โœฆ Synopsis


Ophiobolins A and B (1) are substances constructed from five isoprene units linearly linked head to tail (2). In their biogenetic hypothesis Nozoe et al.

proposed that the introduction of a 3-hydroxyl substituent is accounted for by attack at 3-C by an agent which transfers OH+ (3).

The tricyclic ketone 14, an ophiobolin analogue lacking only the C-ring side chain, was synthesized in optically active form; the key step was the intramolecular NiCl2/CrC12 mediated coupling of 10 to yield 11.
