Beschreibung

Allgemeine Beschreibung

Methyl crotonate undergoes vinylogous aldol reaction with enolizable aldehydes in the presence of aluminum tris(2,6-di-2-naphthylphenoxide).

Anwendung

Methyl crotonate was used to investigate chemoselectivity in the reaction between methyl crotonate and benzylamine catalyzed by lipase B from Candida antarctica using solvent engineering. It was used as starting reagent during the total synthesis of phytotoxins solanapyrones D(1) and E(2).
