New two-step sequence involving a hetero-Diels–Alder and a nonphenolic oxidative coupling reaction: a convergent access to analogs of steganacin
摘要:
A new family of analogs of steganacin, an important antimitotic compound, was accessed. It takes advantage of a completely stereoselective sequence of two key steps. The central dihydropyrane core is built by a highly diastereoselective and facially controlled hetero-Diels-Alder reaction. It is followed by a nonphenolic biaryl oxidative coupling with a complete atropo-stereoselectivity. It leads to a quick way to form cyclic biaryl lignans. (C) 2011 Elsevier Ltd. All rights reserved.
