1-Acetoxy-3-(substituted phenyl)propene compounds

Abstract

1-acetoxy-3-(substituted phenyl)propene compounds represented by the general formula (I): in which formula (I), R 1 and R 2 respectively and independently from each other represent a member selected from the groups consisting of a hydrogen atom and alkyl groups having 1 to 10 carbon atoms, R 1 and R 2 may form, together with carbon atoms located in the 2- and 3-positions of the propene group, a cyclic group; and A represents a member selected from a group of substituted phenyl groups represented by the formulae (II) and (III): wherein R 3 and R 4 respectively and independently from each other represent an alkyl group having 1 to 4 carbon atoms, m represents an integer of 0 or 1 to 4, n represents an integer of 1 to 5 and k represents an integer of 1 or 2.
