Daphnicyclidins J and K, unique polycyclic alkaloids from Daphniphyllum humile.
نویسندگان
چکیده
Two Daphniphyllum alkaloids with unprecedented polycyclic skeletons, daphnicyclidins J (1) and K (2), have been isolated from the stems of Daphniphyllum humile, and the structures and relative stereochemistry were elucidated on the basis of spectroscopic data. The absolute stereochemistry of 1 was established by chemical correlation with a known-related alkaloid, daphnicyclidin D (3), through a modified Polonovski reaction.

متن کاملDaphniphyllum alkaloids: recent findings on chemistry and pharmacology.
The unique polycyclic fused ring systems of Daphniphyllum alkaloids, along with their extensive bioactivities, make this family of alkaloids especially attractive targets for total synthesis and biogenetic studies. Successive discoveries of new alkaloids with unprecedented skeletons have made a great contribution to structural diversities of alkaloids elaborated by plants of the genus Daphniphy...
متن کاملFive new alkaloids from the stem bark of Daphniphyllum macropodum.
Five new alkaloids, daphnicyclidins M and N (compounds 1 and 2) and calyciphyllines Q-S (compounds 3-5), along with four known ones, paxiphylline C (6), macropodumine B (7), macropodumine C (8) and daphnicyclidin A (9) were isolated from the stem bark of Daphniphyllum macropodum. Calyciphylline Q (3) is the first calyciphylline A derivative possessing a double bond between C-18 and C-19. Their ...

Three new Daphniphyllum alkaloids, daphnioldhanins A-C (1-3), along with four known ones, were isolated from the aerial parts of saplings of Daphniphyllum oldhami. The structures of these alkaloids were established by spectroscopic methods. The relative configuration of 1 was further confirmed by a single-crystal X-ray diffraction analysis. In addition, the (1)H and (13)C NMR data of the free b...
