Description

Application

Reactant involved in the synthesis of:
• Methylene-arylbutenones via carbonylative arylation of allenols
• 4-aminoquinoline analogs via Ullman / Suzuki / Negishi coupling
• Primary amino acid derivatives with anticonvulsant activity
• Alkyl arylcarbamates via Cu-catalyzed coupling with potassium cyanate
• Aryl-substituted succinimides and cyclic ketones by asymmetric conjugate addition
• Axially chiral dicarboxylic acids for asymmetric Mannich-type reactions
