Xyloccensins O and P, Unique 8,9,30-Phragmalin Ortho Esters from Xylocarpus granatum

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.
