The Claisen rearrangement of alyl vinyl ether is known as useful reaction for preparations of γ, δ-unsaturated carbonyl compounds. The reaction is a [3, 3]-sigmatropic rearrangement and takes place by a concerted mechanism through a cyclic six-membered transition state.
Through Claisen rearrangement 2, 3-dimethyl-5-methyl-4-hexenal(13) was prepared from isobutyraldehyde(10) and 2-methyl-3-buten-2-ol, and also 3, 3-dimethyl-4-pentanal was prepared from 3-methyl-2-buten-1-ol and ethyl vinyl ether.
