  We have developed a divergent strategy for the synthesis of five- and six-membered lactams via either an amidation of sp3 C-H bonds or electrophilic substitution of arenes via Ir-nitrene intermediates. With the employment of a readily available iridium catalyst in dichloromethane or hexafluoro-2-propanol, a wide range of lactams were synthesized in good to excellent yields with high selectivity.

  A C-N bond forming dearomatization protocol with broad scope is outlined. Specifically, bifunctional amino reagents are used for sequential nucleophilic and electrophilic C-N bond formations, with the latter effecting the key dearomatization step. Using this approach, γ-arylated alcohols are converted to a wide range of differentially protected spirocyclic pyrrolidines in just two or three steps.

• Prenylcoumarin with Rev-export inhibitory activity from Cnidii Monnieris Fructus
  作者：Satoru Tamura、Toshiaki Fujitani、Masafumi Kaneko、Nobutoshi Murakami

  By use of the fission yeast expressing the model fusion protein comprised of GST, SV40 T antigen NLS, GFP, and Rev-NES in the bioassay, the prenylcoumarin osthol (1) was disclosed as the new Rev-export inhibitor from the MeOH extract of Cnidii Monnieris Fructus. Furthermore, 1 was also found to inhibit export the genuine Rev in HeLa cells by indirect fluorescent antibody technique. By the competitive experiment using the biotinylated probe 3, osthol (1) was revealed to inhibit nuclear export of Rev through a NES non-antagonistic mode. Structure-activity relationship analysis of several analogs of 1 clarified that both prenyl side chain and double bond adjacent to the lactone carbonyl residue play an important role in the Rev-export inhibitory potency of 1.
