Formal total synthesis of neodysiherbaine A via a stereoselective [3+2]-annulation strategy
The highly stereoselective synthesis of the hexahydrofuro[3,2-b]pyran core of neodysiherbaine A is described. The key step involves the stereocontrolled formation of the tetrahydrofuran ring via a formal [3 + 2]-annulation between isopropylidene-protected aldehydo-d-ribose and a β-substituted allylsilane mediated by trifluoroborane etherate.
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.
