The structure of .0.0(2,6)]tridec-7-ene-10,11-diol-4,2-carbolactone mo
nohydrate (methyl ano-3,4,4a,6a,-7,8,9,10,10a,10b-decahydro-2H-benzo [
h] chromene-3-carboxylate monohydrate) has been determined. The tricyc
lic compound has the same configuration at C3 (S), C9 (R) and C10 (S)
(steriod numbering) as Veratrum alkaloids. The relative stereochemistr
y is cis for the A/B ring junction, anti between C10 methyl and C9 car
bolactone and cis for the B/C ring junction.
