The syntheses of the angucyclinone antibiotics; (+/-)-rubiginone B1 3 and B2 4, (+/-)-ochromycinone 7, and (+/-)-emycin A 12 are reported.The key step for the constructiuon of the benzoanthracene nucleus in each of the syntheses w
Biosynthesis of PD 116740: Origins of the carbon, hydrogen, and oxygen atoms and derivation from a 6-deoxybenz[a]anthraquinone

The benz[a]anthraquinone antibiotic PD 116740 is formed from the regular cyclization of a decaketide intermediate folded in a manner to generate the angular tetracyclic skeleton. The 6-deoxybenz[a]anthraquinone tetrangulol is an intermediate, indicating t
A stereoselective approach to the angucyclinone antibiotics: A total synthesis of the C-1 epimer of (±)-rubiginone B1
Larsen,O'Shea
, p. 1373 - 1376 (2007/10/02)
A stereoselective Lewis acid-promoted cycloaddition reaction of 5-hydroxy-1,4-naphthoquinone and dienol (12) gave a key intermediate (14) which was transformed into the title compound (18) in 35% overall yield.
