Chapter 23, Problem 19P

Gadoleic acid ( C 20 H 38 O 2 ) , a fatty acid that can be isolated from cod-liver oil, can be cleaved by hydroxylation and subsequent treatment with periodic acid to C H 3 ( C H 2 ) 9 C H O and C H O ( C H 2 ) 7 C O 2 H .

(a) What two stereoisomeric structures are possible for gadoleic acid?

(b) What spectroscopic technique would make possible a decision as to the actual structure of gadoleic acid?

(c) What peaks would you look for?

(a) Draw a skeletal structure of the anabolic steroid 4-androstene-3,17-dione, also called “andro,” from the following description. Andro contains the tetracyclic steroid skeleton with carbonyl groups at C3 and C17, a double bond between C4 and C5, and methyl groups bonded to C10 and C13. (b) Add wedges and dashed wedges for all stereogenic centers with the following information: the configuration at C10 is R, the configuration at C13 is S, and all substituents at ring fusions are trans to each other.
(d) CH,C=C:- + CH,CH,OH
