  Annulation Strategies for Benzo[b]fluorene Synthesis:  Efficient Routes to the Kinafluorenone and WS-5995 Antibiotics

  摘要：

  Intramolecular palladium-mediated arylation approaches to benzo[b]fluorenes have been investigated. The methodology has been applied in a short synthesis of tri-O-methylkinafluorenone, providing an effective alternative td Friedel-Crafts-based approaches. During the course of this work, an acid-promoted quinolactonization of naphthoquinones was also developed, providing direct access to either ortho or para isomers as desired. Application of this methodology in syntheses of the antibiotics WS-5995A, WS-5995C, and functional analogues was demonstrated, and antitumoral activity of this class was determined.

  Application of the BHQ benzannulation reaction to the synthesis of benzo-fused coumarins

  摘要：

  A new approach to the synthesis of the 6H-benzo[d]naphthal[,2-b]pyran-6-one ring system present in the gilvocarcin family of antibiotics is described. The key feature of this approach is the application of a new benzannulation strategy (the 'BHQ Reaction') whereby readily available ortho-allylaryl trichloroacetates are transformed into naphthalene derivatives via a cascade of reactions involving an initial ATRC reaction followed by the extrusion of CO2.

  syntheses of both the benzo[b]phenanthridine and the 6H-dibenzo[c,h]chromen-6-one motif are described. Reaction of (2-(3-bromo-1,4-dimethoxynaphthalen-2-yl)phenyl)methanamine with PIFA afforded benzo[b]phenanthridine-7,12-dione, while the related nonbrominated precursor, (2-(1,4,5-trimethoxynaphthalen-2-yl)phenyl)methanamine on treatment with PIFA, furnished the ortho-quinone 1-methoxybenzo[c]phenanthridine-11

  描述了苯并[ b ]菲啶和6 H-二苯并[ c，h ] chromen-6-一个基序的新颖合成。（2-（3-溴-1,4-二甲氧基萘-2-基）苯基）甲胺与PIFA的反应制得苯并[ b ]菲啶-7,12-二酮，而相关的非溴化前体是（2-（1，用PIFA处理4,5-三甲氧基萘-2-基）苯基）甲胺，得到邻-醌-1-甲氧基苯并[ c ]菲啶-11,12-二酮。出乎意料的是，在O 2气氛下用NBS处理相关的氧类似物，例如（2-（1,4-二甲氧基萘-2-基）苯基）甲醇，得到色酮12-甲氧基-6 H-二苯并[ c，h]] chromen-6-one。
