Abstract

1-Chloro-2-methyl-4-acyloxy-2-butene derivatives can be synthesized in good yields and high purity starting from isoprene and employing a chlorohydrin formation reaction in a system made of N-chloroisocyanuric acid derivatives and water, followed by esterification and rearrangement of the crude product mixture.
