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.
High purity grade.
