Stereocontrolled Syntheses of Diequatorial and Axial-Equatorial Furofuran Lignans
摘要:
Methyl piperitol, a representative example of the diequatorial furofuran lignan, was synthesized in a good overall yield based on a highly stereocontrolled conjugate addition-aldol reaction. Fargesin, a representative example of the axial-equatorial furofuran lignans, was also synthesized in a good overall yield based on a new method for inversion of the stereochemistry at C-4 of 5a.
Fargesin, a representative example of the axial-equatorial furofuran lignans, was synthesized in a good overall yield based on a new method for inversion of the stereochemistry at C-4 of1.
