ABSTRACT
A protocol for one-pot Claisen rearrangement with n-butyl vinyl ether is described. Upon heating allylic alcohols with excess n-butyl vinyl ether with catalytic amount of Hg(OAc)2 and NaOAc, Claisen rearrangement takes place through in situ formation of the requisite allyl vinyl ether.
ACKNOWLEDGMENT
The authors thank Mr. Takeshi Kuboyama for an experimental data of the large-scale reaction.
