| titleOfInvention | Method for synthesizing chiral cyclic urea through asymmetric hydrogenation of iridium-catalyzed 2-hydroxypyrimidine compound |
| abstract | The invention provides a chiral ring synthesized by asymmetric hydrogenation of an iridium-catalyzed 2-hydroxypyrimidine compoundA process for the preparation of urea-like compounds, in the formula: r is C1-C6 alkyl or aryl; r' is aryl, heteroaryl or alkyl containing substituent groups, wherein the substituent groups are F, Cl and CF 3 Me and MeO. The synthesized chiral cyclic urea has an enantiomeric excess of 96%. The method has the advantages of simple, convenient, practical and feasible operation, high yield, environment friendliness, commercial availability of the catalyst, mild reaction conditions and potential practical application value. |
