Pimelotides A and B, diterpenoid ketal-lactone orthoesters with an unprecedented skeleton from Pimelea elongata.
A detailed investigation of the minor phytochemical components of Pimelea elongata foliage led to the discovery of two new diterpenoid daphnane ketal-lactone orthoesters with an unprecedented skeleton, pimelotides A (1) and B (2). Their structures and relative configurations were elucidated by NMR spectroscopy.
