Phosphine-catalyzed [3 + 2]-annulation of Morita–Baylis–Hillman carbonates with benzofuran-derived azadienes: Synthesis of spiro-cyclopentane benzofurans
Herein, a phosphine-catalyzed [3 + 2] cycloaddition of Morita–Baylis–Hillman carbonates and benzofuran-derived azadienes has been achieved. A wide range of functionalized spiro-cyclopentane benzofurans were obtained in moderate to great yields (36–65 % yields) with moderate to excellent diastereoselectivities (3.6:1->20:1 drs). The protocol is characterized by easy operation, and broad functional group tolerance. Furthermore, the versatility of this methodology was further demonstrated through gram-scale synthesis and a synthetic transformation of the resulting product.
期刊介绍:
Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry.
Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters.
Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
