New Podophyllotoxin Derivatives as Potential Anticancer Agents: Synthesis and Cytotoxicity of 4β-O-Propenylpodophyllotoxin Ethers
摘要:
4 beta-O-Propenylethers of podophyllotoxin 3a-e were prepared from 4-chloro-4-deoxypodophyllotoxin 2 and allylic alcohols. Cytotoxicity of these compounds against KB cells is reported.

Site-specific introduction of deuterium is important in organic and medicinal chemistry. Herein, we present an electrochemical method for the deuterodehalogenation of aryl and heteroaryl benzylic halides, using inexpensive deuteriumoxide as the deuterium source. We also uncover a sequential paired electrolysis regime, which permits switching between net reductive and overall redox-neutral reactions
