First enantioselective synthesis of (R)-Convolutamydine B and e with N-(Heteroarenesulfonyl)prolinamides
Enantioselective synthesis of (R)-convolutamydine B and E by the reaction of actaldehyde with ketones using organocatalysts was reported. The reaction of 4,6-dibromoisatin with acetaldehyde was examined in presence of various chiral organo-catalysts. The
