Asymmetric radical synthesis of 2,5-diaryl-2,3-dihydrofurans - Application to the preparation of (+)-phyltetralin
Garzino, Frederic,Meou, Alain,Brun, Pierre
, p. 1410 - 1414 (2007/10/03)
The diastereoselective MnIII-promoted radical addition of βoxo ester 1 onto N-cinnamoyloxazolidinone 2 affords, after removal of the chiral auxiliary, the enantiopure 2,5-diaryl2,3-dihydrofuran (-)-4. Its SnCl4-induced rearrangement
The Synthesis of Lignans and Related Structures using Quinodimethanes and Isobenzofurans: Approaches to the Podophyllins
Mann, John,Piper, Susan E.,Yeung, Lilan K.P.
, p. 2081 - 2088 (2007/10/02)
Novel routes to 1-aryl-5,6-dialkoxy-1,3-dihydrobenzothiophene 2,2-dioxides (13) and to the corresponding benzofuran (8) have been developed; these species yield quinodimethanes (12) via thermal extrusion of SO2 and isobenzofurans (5c) in an acid-cat
The Preparation of Lignans via Intermolecular Cycloadditions with Quinodimethanes
Mann, John,Piper, Susan E.
, p. 430 - 432 (2007/10/02)
Certain lignans can be prepared using, as the key step, a thermal reaction between 1-(aryl)-1,3-dihydro-5,6-dialkoxy-benzothiophen 2,2-dioxides and dienophiles.
Synthesis of Aryltetralin and Dibenzylbutyrolactone Lignans: (+/-)-Lintetralin, (+/-)-Phyltetralin, and (+/-)-Kusunokinin
Ganeshpure, Pralhad A.,Stevenson, Robert
, p. 1681 - 1684 (2007/10/02)
Application of a general synthetic pathway for aryltetralin and dibenzylbutyrolactone lignans, starting from the lithium enolate of 3-(3,4-dimethoxybenzyl)butyrolactone (1) led to syntheses of (+/-)-lintetralin (4), (+/-)-phyltetralin (5), (+/-)-isogalcat
STRUCTURE AND SYNTHESYS OF HYPOPHYLLANTHIN, NIRTETRALIN, PHYLTETRALIN AND LINTETRALIN
Ganeshpure, Pralhad A.,Schneiders, Gail E,Stevenson, Robert
, p. 393 - 396 (2007/10/02)
Structures propounded for the four aryltetralin lignan constituents isolated from Phyllanthus niruri Linn. are confirmed by syntheses of their (+/-)-forms.
