General description

cis-1,4-Diacetoxy-2-butene is an ester. Ruthenium olefin metathesis catalysts having cyclic (alkyl)(amino)carbenes effectively catalyzes the cross-metathesis of cis-1,4-diacetoxy-2-butene with allylbenzene. cis-1,4-Diacetoxy-2-butene on pyrolysis affords 1-acetoxy-1,3-butadiene, a diacetate and an isomeric 1,2-diacetoxy-3-butene. Mechanism of pyrolysis has been investigated.

Application

cis-1,4-Diacetoxy-2-butene may be used in the preparation of hindered Diels-Alder adducts. It may be used for the synthesis of 1,2,3,4-tetrahydro-2-vinylquinoxalines, via Palladium-catalyzed tandem allylation of 1,2-phenylenediamines.

Hindered Diels-Alder adducts have been prepared from 3,6-dibromophencyclone, 2, with cis-1,4-diacetoxy-2-butene, 3; cis-2-butene-1,4-diol, 4; and N-benzylmaleimide, 5. The adduct from the parent phencyclone, 1, with N-benzylmaleimide was prepared for comparison. One- and two-dimensional (1D and 2D) proton and carbon-13 NMR
