FACILE SYNTHESIS OF AVICEQUINONE-B NATURAL PRODUCT
摘要:
An efficient synthesis of avicequinone-B (2) and furonaphthoquinone 4 has been carried out starting from 2-hydroxy-1,4-naphthoquinone (6) by CAN-mediated cycloaddition reaction.

Ceric(IV) ammonium nitrate-mediated oxidative cycloaddition of 1,3-dicarbonyls to vinylsulfides afforded substituted dihydrofurans with sulfide groups in moderate yields. This new synthetic method has been applied to thesynthesis of benzo[b]naphtho[2,3-d]furan-6,11-dione and furanoflavone natural products such as millettocalyxins C and pongol methyl ether.
