Reformatsky Reaction of Methyl -Bromoisobutyrate with 2-Oxo-2H-benzo[f]chromene-3-carboxylic Acid Esters and N-Benzylamide
摘要:
Reformatsky reagent derived from methyl alpha-bromoisobutyrate reacts with methyl and ethyl 2-oxo-2H-benzo[f]chromene-3-carboxylates and N-benzyl-2-oxo-2H-benzo[f]chromene-3-carboxamide to afford the corresponding derivatives of 4-(1-methyl-1-methoxycarbonylethyl)-2-oxo-3,4-dihydro-2H-benzo[f]chromene-3 carboxylic acid as a single stereoisomer.
