Xyloccensins O and P, unique 8,9,30-phragmalin ortho esters from Xylocarpus granatum

Org Lett. 2004 May 27;6(11):1841-4. doi: 10.1021/ol049444g.

Abstract

Two unique 8,9,30-phragmalin ortho esters, xyloccensins O (1) and P (2), were isolated from the mangrove plant Xylocarpus granatum. They are a new type of ortho ester of phragmalin. The structures were determined by spectroscopic and single-crystal X-ray diffraction techniques. The biogenetic pathway to these new phragmalins was also proposed. [structure: see text]
