Organocatalytic asymmetric syntheses of functionalized tetrahydropyridazines
摘要:
Four tetrahydropyridazines, respectively, substituted at the C-3 position with hydroxymethyl, a silyloxymethyl, a carboxylic acid, and a methyl ester have been prepared in good yields and high enantiomeric purities using organocatalytic alpha-amination of aldehydes as the key step. These compounds have then been tested as organocatalysts for the same reaction. (C) 2010 Elsevier Ltd. All rights reserved.
