  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.

  The Michael addition reaction of lithium salt of cyanohydrin to (S)- and (R)-3-(2,2-dimethyl-1,3-dioxolan-4-yl)-cis-2-propenoate (2 and 3) proceeded in 93% de in the presence of two equivalents of HMPA at -100 degrees C. This diastereoselectivity could be elucidated by the stereocontrol based on the 1,3-allylic strain. Utilizing this reaction, stereocontrolled syntheses of (+)-fargesin (6) and (-)-picropodophyllone (7) were achieved. (C) 1997 Elsevier Science Ltd.

  An efficient method for stereocontrolled syntheses of the unsymmetrically substituted bislactone subgroup of the furofuran lignan has been developed based on a stereoselective aldol reaction of the acid anhydride 8 or 9 and an aromatic aldehyde employing methyl 4,8-dioxoxanthoxylol (1a), 4,8-dioxofargesin (1b), methyl 4,8-dioxopiperitol (2a) and their isomer 3a as the representative examples of the axial-equatorial 1, diequatorial 2, and diaxial 3 types of this series.
