摘要：
Reactions of beta-methylfuran and 2,4-dimethylfuran with ethyl diazoacetate in the presence of [Rh-2(OAc)(4)] catalyst, followed by iodine-induced isomerization, yielded furan ring-unravelled products. The results are compared with those of alpha-methylfurans. (C) 1999 Elsevier Science Ltd. All rights reserved.
