标题:Synthesis And Properties Of 2-Cyanoethoxy Derivatives Of Dammarane Triterpenoids
摘要:Cyanoethylation Of Dammaran-3 Beta-Ols And 3-Oxime Dammarene,Semisynthetic Derivatives Of The Natural Dipterocarpol,Afforded A Series Of New Dammarane Triterpenoids Containing 2-Cyanoethoxy Fragment At The Carbon Atom In The Position 3 Of The Tetracyclic Scaffold. A Notable Antiviral Activity Was Found In 20(S)-3-[(2-Cyanoethoxy)Imino]-Dammar-24-En-20-Ol And 20(S)-3-D-(2-Cyanoethyl)-25,26,27-Trinor-20,24-Olidedammarane.
