- Acyclic Stereocontrol in the Catalytic C-H Amination of Benzylic Methylene Groups
[作者:NOERDER ANIKE; HERRMANN PAVEL; HERDTWECK EBERHARD; BACH THORSTEN,期刊:Organic Letters, 页码:3690-3692 , 文章类型: Article,,卷期:2010年12-16]
- Diastereotopos-differentiation is the key feature of the catalytic C-H amination at the benzylic position of substrate 1. Essentially independent of the functional group X (X = COOMe, PO(OEt)(2), SO2Ph, NO2, CN, OAc), th...
- Use of N-Allylidene-1,1-diphenylethanamine as a Latent Acrolein Synthon in the Double Nucleophilic Addition Reaction of Ketene Silyl (Thio)acetals and Allylborolanes
[作者:SHIMIZU MAKOTO; KAWANISHI MAMI; MIZOTA ISAO; HACHIYA IWAO,期刊:Organic Letters, 页码:3571-3573 , 文章类型: Article,,卷期:2010年12-16]
- In the presence of silica gel and water, a mixture of ketene silyl acetals and 2-allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane underwent 1,4- and subsequently 1,2-addition with N-allylidene-1,1-diphenylethanamine to give...
