Diels-Alder reaction of furan with methyl 3-bromopropiolate: a route to methyl 3-oxo-7-oxabicyclo[2.2.1]hept-5-en-2-carboxylate
摘要:
The two epimers of methyl 3-oxo-7-oxabicyclo[2.2.1]hept-5-en-2-carboxylate have been prepared from furan and methyl 3-bromopropiolate as a methoxycarbonylketene equivalent. The final step required hydrolysis of acetals by Nafion-H.
