Reaction de Reformatsky a froid avec des α-bromoesters-acetals. I. Une methode generale pour la synthese des β-hydroxyacides a partir des α-bromoesters de tetrahydropyrannyle (Note de laboratoire)

Bogavac, M.,Arsenijevic, L.,Arsenijevic, V.

, p. 145 - 147 (2007/10/02)

The readily accessible tetrahydropyranyl esters of α-bromoacids can be used in the Reformatsky reaction for the preparation of β-hydroxyacids.The reaction is generally carried out in cold tetrahydrofuran.The β-hydroxyacids can be easily obtained by stirring the cold solution of their tetrahydropyranyl esters with dilute hydrochloric acid.
