1-METHOXY-3-TRIMETHYLSILOXY-1,3-BUTADIENE Chemical Properties,Usage,Production

Uses

1-Methoxy-3-trimethylsiloxy-1,3-butadiene is employed as a reagent in Mannich-Michael reaction for the synthesis of piperidinones and enaminones. As Diels-Alder diene, it is used in the synthesis of pyridones and pyranones, sulfone analogues of griseofulvin (sulfogriseofulvins) and 4H-1-aminopyrroles and 4, 5H-pyrazoles.

General Description

trans-1-methoxy-3-trimethylsiloxy-1,3-butadiene is a funtionalized Diels-Alder diene. Mukaiyama-Michael-type addition/heterocyclization of trans-1-methoxy-3-trimethylsiloxy-1,3-butadiene (Danishefsky′s diene) with 1,2-diaza-1,3-butadiene has been investigated. Asymmetric hetero-Diels-Alder cyclization of Danishefsky′s diene with benzaldehyde catalyzed by mesoporous inorganic/metalorganic hybrid materials has been reported.

Purification Methods

It may contain up to 1% of the precursor 4-methoxybut-4-ene-2-one. It is easily purified by distilling through a Vigreux column (p 11) in a vacuum and taking the middle fraction. [Danishefsky & Kitihara J Am Chem Soc 96 7807 1974, Danishefsky Acc Chem Res 14 400 1981.]
