Abstract
The shielding values in 13C
N.M.R. spectra of the ecdysteroids dacrysterone, pterosterone, and ponasterone
C have been assigned, together with those for the 20,22- and 22,24-benzylidene
acetal derivatives of the latter. From the N.M.R. data the C24 configuration of
dacrysterone is assigned as 24R, while the 24s configuration is assigned to
pterosterone and ponasterone C.
