Descrição

Descrição geral

(1S)-(+)-Ketopinic acid is a chiral ketone.

Aplicação

(1S)-(+)-Ketopinic acid may be used to prepare:

• Chiral phosphine-oxazoline ligands, which can used in asymmetric palladium-catalyzed Heck reaction of aryl or alkenyl triflates with cyclic alkenes.
• A chiral imino-phosphine ligand, which can be used in palladium-catalyzed asymmetric Diels–Alder reactions to prepare six-membered carbocycles.
• A chiral iminopyridine ligand, which can be used in copper-catalyzed Henry (nitro aldol) reaction between nitromethane and o-anisol to form the corresponding β-hydroxynitroalkane.

Used to prepare a new chiral oxazolidone auxiliary and a ketopinic derivatized polymer used for the deracemization of amines. Starting material for the synthesis of homochiral 2,10-camphanediols. Employed in the formation of a chiral Schiff base precursor to diethyl (S)-α-amino-α-alkyl phosphonates.
