Propargylic cation-induced intermolecular electrophilic addition-semipinacol rearrangement

4 May, 2014 - 20:17

Chem. Commun., 2014, 50,5691-5694
DOI: 10.1039/C3CC49650C, CommunicationHui Shao, Xiao-Ming Zhang, Shao-Hua Wang, Fu-Min Zhang, Yong-Qiang Tu, Chao Yang
A novel propargylic electrophile-induced tandem intermolecular addition-semipinacol rearrangement was developed for the synthesis of a series of synthetically useful [small beta]-propargyl spirocyclic ketones. Its synthetic application was demonstrated by efficient construction of the key tricyclic moiety of daphlongamine E.

Practical access to spiroacetal enol ethers via nucleophilic dearomatization of 2-furylmethylenepalladium halides generated by Pd-catalyzed coupling of furfural tosylhydrazones with aryl halides

4 May, 2014 - 20:17

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC01725K, CommunicationBiaolin Yin, Xiaoyu Zhang, Jianchao Liu, Xuehui Li, Huanfeng Jiang
Pd-catalyzed coupling of furfural tosylhydrazones with aryl halides produces 2-furylmethylenepalladium halides, which undergo intramolecular nucleophilic dearomatization to provide spiroacetal enol ethers.
