Application
trans-1,4-Dichloro-2-butene was used as starting reagent in the synthesis of trans-tetrahydrofuran (THF) ring building block. It was also employed in the chemical synthesis of swainsonine [(1S,2R,8R,8 αR)-trihydroxyindolizidine] and 9-alkylpurines.

The chemical synthesis of swainsonine [(1S,2R,8R,8 alpha R)-trihydroxyindolizidine] from trans-1,4-dichloro-2-butene was previously described [Adams, C. E., Walker, F. J., & Sharpless, K. B. (1985) J. Org. Chem. 50, 420-424]. A modification of that synthesis provided two other isomers, referred to

Chirality, 12(7), 581-589 (2000-06-22)
A highly efficient synthetic method for the trans-tetrahydrofuran (THF) ring building block was established and the title compound was synthesized in 19 steps from trans-1,4-dichloro-2-butene via a convergent route with a Wittig reaction as the key step.

Alkylation of adenine (5a) or 2-amino-6-chloropurine (5b) with excess trans-1,4-dichloro-2-butene (4), effected by K2CO3 in dimethyl sulfoxide or tetra-n-butylammonium fluoride in tetrahydrofuran, led in 90-95% regioselectivity to 9-alkylpurines 6a and 6b. The title compounds 2a and 2b were obtained by
Initial study in rats evaluating the effects of 1,4-dichlorobutene-2 (DCB) on the respiratory tract.

Drug and chemical toxicology, 25(2), 227-230 (2002-05-25)
Rats were exposed by inhalation to either 0.5 ppm 1,4-dichlorobutene-2 (DCB) for two years or to 5.0 ppm for seven months, 2.5 ppm for five months, and no further exposure for 12 months prior to sacrifice. Malignant and non-malignant tumors

Several important chemicals, including formaldehyde, 1,4-dichloro-2-butene, bis-chloromethyl ether, hexamethylphosphoramide, and epichlorohydrin have been shown to produce nasal tumours in rats following repeated or continuous inhalation exposures. Some of these compounds are respiratory irritants. To determine whether there is a correlation
