Selective syntheses of cyclobutane-β-aminocarboxylic acid derivatives by the ruthenium complex-catalyzed reaction of allylamines with acrylic compounds
Allylamines react with acrylic compounds in the presence of Ru(cod)(cot) catalyst to give cyclobutane-β-amino acid derivatives in high yield (up to 85%); cod = cycloocta-1,5-diene, cot = cycloocta-1,3,5-triene.
