Synthesis of Solanesylamine Derivatives(I) --Synthesis of N,N-Di(acyloxyethyl)solanesylamine

Solanesyl bromide(Ⅱ) was reacted with diethanolamine to give solanesyl diethanolamine(Ⅲ) which was acylated with 3,4,5 trimethoxybenzoyl chloride, acetic anhydride, benzoyl chloride and cinnamyl chloride to give N,N di[(3,4,5 trimethoxybenzoyloxy)ethyl]solanesylamine(Ⅳ), N,N di[(acetyloxy)ethyl] solanesylamine(Ⅴ), N,N di[(benzoyloxy)ethyl]solanesylamine(Ⅵ), N,N di[(cinnyloxy)ethyl]solanesylamine(Ⅶ) respectively. The structures of compounds Ⅲ～Ⅶ were confirmed by IR, 1H NMR, MS and elemental analysis.
