Ag. Michel et M. Drouin, STRUCTURE OF 3-EPIRYANODOL - A HEPTAHYDRO DITERPENE, Acta crystallographica. Section C, Crystal structure communications, 49, 1993, pp. 1685-1688
As part of an investigation of structure-activity relationships of rya
noids, the crystal structure of 3-epiryanodol was carried out in order
to confirm its stereochemistry Ryanodol has 11 asymmetric C atoms. Th
e C3 atom, which has R stereochemistry in the natural product, was inv
erted to the S stereochemistry to give this 3-epimer of ryanodol. The
compound makes three inter- and four intramolecular hydrogen bonds.
