Daphnezomines T--V, alkaloids from Daphniphyllum humile.
Three new Daphniphyllum alkaloids, daphnezomines T-V (1-3), were isolated from the leaves and branches of Daphniphyllum humile (Daphniphyllaceae). The structures and relative stereochemistry of 1-3 were elucidated on the basis of spectroscopic data. Daphnezomine T (1) is the first alkaloid without a branched C(1) unit at C-5 among all Daphiniphyllum alkaloids reported so far.
