Chemistry is traditionally divided into organic and inorganic chemistry. name: (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 126456-43-7
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).
