The object of the present invention is to provide an industrial and economical process for preparing (E2)-cis-6,7-epoxy-2-nonenal of the following formula (3):
The present invention provides a process for preparing (E2)-cis-6,7-epoxy-2-nonenal (3), comprising at least steps of:
subjecting (Z3,Z6)-3,6-nonadien-1-ol of the following formula (1) to oxidation:
to form (E2,Z6)-2,6-nonadienal of the following formula (2); and
epoxidizing the resulting (E2,Z6)-2,6-nonadienal to form the aforesaid (E2)-cis-6,7-epoxy-2-nonenal (3).
本发明的目的是提供一种工业和经济的方法,用于制备以下式(3)的(E2)-顺式-6,7-环氧-
2-壬烯醛:本发明提供了一种制备(E2)-顺式-6,7-环氧-
2-壬烯醛(3)的方法,包括至少以下步骤:将以下式(1)的(Z3,Z6)-3,6-
壬二烯-1-醇氧化以形成以下式(2)的(E2,Z6)-2,6-壬二烯醛;并将所得的(E2,Z6)-2,6-壬二烯醛环氧化以形成上述的(E2)-顺式-6,7-环氧-
2-壬烯醛(3)。
