3-alpha-L-rhamnopyranoside (8) and 3 beta-(alpha-L-rhamnopyranosyloxy)-5 alpha-pregn-14-en-20-one (14) were prepared from uzarigenin by ozonolysis followed by zinc and acetic acid reduction and glycosidation. During the glycosidation reaction leading to (8) the corresponding ortho ester (9) was also obtained. Uzarigenin alpha-L-rhamnopyranoside (15) also was prepared.

e) is described. This novel steroid is about 10 times more potent than progesterone and one-tenth as potent as ouabagenin in an [3H]ouabain radioligand binding assay and is the first in a series of progesterone congeners that interact at the cardiac glycoside receptor both to possess the C/D cis ring junction and to enhance contractility of isolated cardiac tissue.
