In homogeneous catalysis, catalysts are in the same phase as the reactants. Chemistry is traditionally divided into organic and inorganic chemistry. Quality Control of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.

Enantioselective synthesis of densely functionalized pyranochromenes via an unpredictable cascade Michael-oxa-Michael-tautomerization sequence
A surprising example of enantioselective cascade Michael-oxa-Michael- tautomerization reactions of malononitrile and benzylidenechromanones has been developed. In this case, malononitrile functions as both nucleophile and electrophile. Meanwhile, a simple bifunctional indane amine-thiourea catalyst has been discovered to promote this process to afford high yields (up to 99%) and high to excellent enantiomeric excesses (81-99% ee).
