A Novel Synthesis of Chiral DBU/DBN-related Molecules for Use in Asymmetric Base Catalysis
摘要:
The synthesis of sterically hindered chiral DBU/DBN-related molecules (6) from (+)-camphor lactam (1) is described. The value of the products as chiral organic base catalysts is exemplified by their use in asymmetric Michael addition reactions of beta -keto ester (7).
