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
Synthetic approaches to the angucycline antibiotics: the total syntheses of (+/-)-rubiginone B1 and B2, (+/-)-emycin A, and related analogues

Directed ortho metalation reactions. Convergent synthesis of "angular" anthracyclinones ochromycinone and X-14881 C
Katsuura, K.,Snieckus, V.
, p. 124 - 130 (2007/10/02)
Convergent syntheses of the benzanthraquinone natural products X-14881 C (2c) and ochromycinone (2d) have been achieved using aromatic directed metalation strategies.Key steps involve (a) the condensations of dilithiated cis-tetralol (13a) with the ald

Katsuura, K.,Snieckus, V.
, p. 9 - 12 (2007/10/02)
The synthesis of the benzanthraquinone natural products X-14881 C (1c) and ochromycinone (1a) via an aromatic directed metalation strategy (Scheme 1) is described.
