Electric Literature of 126456-43-7, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 126456-43-7, Name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol,introducing its new discovery.
Lipase-mediated kinetic resolution of cis-1,2-indandiol 5 in the presence of lipase PS was examined. Enantiomerically enriched (1S,2R)-2-acetoxy-1-indanol 6a was obtained when cis-1,2-indandiol 5 was treated with one equivalent of vinyl acetate. Treatment of 5 with two equivalents of vinyl acetate furnished a mixture of (1R,2S)-2-acetoxy-1-indanol 6a and (1R,2S)-1-acetoxy-2-indanol 6b. A route to both enantiomers of 1 was also developed by using the enantiomerically enriched mono-acetate thus obtained.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation.
