REACTION OF 4-BROMOALKYL-4-METHOXY-2,5-OXAZOLIDIONE WITH ALCOHOL OR α-AMINO ACID ESTER AND TRANSFORMATIONS OF THE PRODUCTS
Reaction of N-carboxy α-dehydroamino acid anhydride with methanol in the presence of NBS gave 4-bromoalkyl-4-methoxy-2,5-oxazolidone, which was further treated with alcohol or α-amino acid ester to give extremely different two types of products, 2-oxazoli
SYNTHESIS OF NEW 2-OXAZOLINONES FROM N-CARBOXY α-DEHYDROAMINO ACID ANHYDRIDES
Addition of methanol to N-carboxy α-dehydroamino acid anhydride in the presence of NBS, followed by the treatment of the resulting product with base gave a new 2-oxazolinone-4-carboxylate.
