Direct catalytic diastereoselective Mannich reactions: the synthesis of protected alpha-hydroxy-beta-aminoketones
The combination of Mg(ClO4)2, 2,2′-bipyridine and N-methylmorpholine generates an effective catalyst system for the direct addition of α-carbonate-substituted ketones to aryl N-Ts imines. Methyl-carbonate-substituted ketones deliver acyclic α-hydroxy-β-aminoketone derivates, while ketones substitute...
