Reaction Steps
As in Example 4, 2-bromocyclopentene-1-carboxaldehyde was converted to (2E,4E)-3 Methyl-5-(2-((E)-2(2,6,6-trimethyl-1-cyclohexen-1-yl)ethenyl)-1-cyclopenten-1-yl)-2,4-pentadienoic acid ethyl ester which on hydrolysis with base gave (2E,4E)-3-Methyl-5-(2-((E)-2 (2,6,6-trimethyl-1-cyclohexen-1-yl)ethenyl)-1-cyclopenten-1-yl)-2,4-pentadienoic acid.
