Abstract
Three new rearranged taxane diterpenoids with 5/7/6-membered ring system were isolated from the bark of Taxus chinensis var. mairei (1 and 2) and the needles of T. cuspidata (3). The structures of them were established as 2α,7β-diacetoxy-5α, 10β, 13α, 15-tetrahydroxy-4β(20)-epoxy-9α- benzoyloxy-11-(15→1)abeotax-11-ene (1), 2α,4α-diacetoxy-7β-benzoyloxy- 5β,20-epoxy-9α, 10β,13α, 15-tetrahydroxy-11(15→1)abeotax-11-ene (2), and 4α,7β-diacetoxy-2α-benzoyloxy-5β,20-epoxy-9α,10β,13α, 15-tetrahydroxy- 11 (15→1)abeotax-11-ene (3) on the basis of spectral data including 2D NMR spectroscopies.
