CALODENDROLIDE, A DEGRADED LIMONOID FROM CALODENDRUM CAPENSE

Calodendrolide, C15H16O4, has its epoxide beta oriented and its 3'-fur yl group alpha oriented. There are three independent molecules in the asymmetric unit, differing principally in the conformation of the 3'-f uryl group with respect to the remainder of the molecule. One molecule has its 3'-furyl O atom alpha oriented, with an O-C-C=C torsion angle of 30.7 (4)degrees, while the other two molecules have their 3'-furyl O atoms beta oriented, with O-C-C=C torsion angles of -136.9 (3) and -134.5 (3)degrees. The epoxide is asymmetric, with mean C-O distances of 1.436 (2) and 1.464 (2) Angstrom.
