Stereoselective synthesis of 4α-Alkyloxy-2-α/β- bromopodophyllotoxin derivatives as insecticidal agents

Xu, Hui,Wang, Qingtian,Guo, Yong

, p. 8299 - 8303 (2011/09/13)

Interesting insecticides: 4α-Alkyloxy-2α/β- bromopodophyllotoxin derivatives were readily prepared with excellent stereoselectivity due to intramolecular steric effects (see scheme). The ratio of two stereoisomers, 2α/β-bromo-4-O- tetrahydropyranylpodophyllotoxin, could be well controlled by the reaction temperature. Copyright
