Reduction with NaBH4 and re-chromatography produced pure methyl DL -13-hydroxy-9 cis -octadecenoate. Methyl DL -19-hydroxy- all cis -8,11,14-eicosatrienoate was prepared by extension of the carbon chain of 5-chloro-2-pentanone, as acetal, by two 2-propynyl units to 10-oxo-2,5-...
[4- 2H 2] and [3- 2H 2]oleates were both obtained from methyl 7- cis-hexadecenoate, exchange of the 伪 protons and chain extension gave the [4- 2H 2] ester and reduction with lithium aluminum deuteride and chain extension gave the [3- 2H 2] ester....
