Ruthenium-Catalyzed [2 + 2] Cycloadditions of Ynamides
摘要:
[GRAPHICS]Ruthenium-catalyzed [2 + 2] cycloadditions between norbornene and ynamides were investigated. The ynamide moiety was found to be compatible with the ruthenium-catalyzed cycloaddition conditions, giving the corresponding cyclobutene cycloadducts in moderate to good yields (up to 97%).
