A taxane with an amino-side chain on C-5 was identified for the first time from rooted cuttings of the Canadian yew, Taxus canadensis. The structure was characterized as 2α,10β,13α-triacetoxy-5α-[3'-(N-formyl- Nmethylamino)-3'-phenylpropanoyloxy]taxa-4(20),12-dien-9α-ol (1) on the basis of 1D and 2D NMR data and HR-FAB-MS analyses. The spectra revealed that in CDCl3 solution 1 was composed of two rotamers (1a and 1b) in a ratio of approximately 1:1. © 2013 Springer Science+Business Media New York.
