SYNTHESIS OF ORYZALEXINS A, B AND C, THE DITERPENOIDAL PHYTOALEXINS ISOLATED FROM RICE BLAST LEAVES INFECTED WITH PYRICULARIA ORIZAE

Naturally occurring enantiomers of three diterpenes isolated as phytoalexins from rice blast leaves were synthesized: (+)-oryzalexin.A (ent-3β-hydroxyisopimara-8(14), 15-dien-7-one,1), (+)-oryzalexin B (ent-7α-hydroxyisopimara-8(14), 15-dien-3-one,2) and (+)-oryzalexin C (ent-isopimara-8(14), 15-diene-3,7-dione, 3).Their antipodes were also synthesized.
