摘要:In This Study We Used Sequential Catalysis-Pph3-Catalyzed Nucleophilic Addition Followed By Pd(0)-Catalyzed Heck Cyclization-To Construct Complex Functionalized Alkylidene Phthalans Rapidly,In High Yields,And With Good Stereoselectivities (E/z Ratios Of Up To 1:22). The Scope Of This Michael-Heck Reaction Includes Substrates Bearing Various Substituents Around The Alkylidene Phthalan Backbone. Applying This Efficient Sequential Catalysis,We Accomplished Concise Total Syntheses Of 3-Deoxyisoochacinic Acid,Isoochracinic Acid,And Isoochracinol.
