Yamakawa, Koji published the artcileStudies on the terpenoids and related alicyclic compounds. XXIII. Total synthesis of (±)-phomenone, (±)-3-epiphomenone, (±)-ligularenolide, and (±)-furanoligularanone, Application In Synthesis of 31253-08-4, the publication is Chemical & Pharmaceutical Bulletin (1980), 28(11), 3265-74, database is CAplus.
(±)-Phomenone (I, Z = α-OH,β-H), (±)-3-epiphomenone (I, Z = α-H,β-OH) (±)-ligularenolide (II), and (±)-furanoligularanone (III) were prepared from naphthalenedione IV via the monoketals V (R = CMe:CH2) or VI. E.g., epoxidation of V (R = CMe:CH2) gave V (R = 2-methyl-2-oxiranyl), whose ring cleavage in the presence of LiNEt2 gave V [R = HOCH2C(:CH2)], epoxidation of which gave I (Z = OCH2CH2O), whose deketalization followed by NaBH4 reduction gave (±)-3-epiphomenone (I, Z = α-H, β-OH).
