3-{4-[3-oxo-3-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propenyl]-phenyl}-propionic acid → 3-{4-[3-oxo-3-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propyl]-phenyl}-propionic acid

Participants

Reaction Steps

A mixture of 3-{4-[3-oxo-3-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propenyl]-phenyl}-propionic acid (121 mg, 0.32 mmol), Pd/C (40 mg, 10% Pd) in ethanol (8 mL) is stirred at rt under 1 bar H2. The reaction mixture is filtered, the filtrate is evaporated to give 3-{4-[3-oxo-3-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propyl]-phenyl}-propionic acid (120 mg) as a pale yellow oil; LC-MS: tR=1.07 min, [M+1]+=383.17.
