New nitrogen derivatives of podophyllotoxin and a novel access to dehydroanhydropicropodophyllin
De Lima,Raslan,De Oliveira
, p. 2675 - 2683 (1994)
The new compounds podophyllotoxone oxime (3) and epipodophyllotoxin azide (5) were prepared. The known dehydroanhydropicropodophyllin (6) was unexpectedly obtained from podophyllotoxin (1) by treatment with TMSCl/NaI/MeCN.
Synthesis of biaryls via palladium-catalyzed [2+2+2] cocyclization of arynes and diynes: Application to the synthesis of arylnaphthalene lignans
Sato, Yoshihiro,Tamura, Takayuki,Kinbara, Atsushi,Mori, Miwako
, p. 647 - 661 (2008/02/09)
A novel method for construction of biaryls via palladium(0)-catalyzed [2 + 2 + 2] cocyclization of diynes and arynes was developed. By this [2+2+2] cocyclization, various arylnaphthalene derivatives, including a sterically hindered 2,2′-disubstituted-1,1′
In vivo immunosuppressive activity of some cyclolignans
Gordaliza, Marina,Castro, M. Angeles,Miguel del Corral, Jose M.,Lopez-Vazquez, M. Luisa,San Feliciano, Arturo,Faircloth, Glynn T.
, p. 2781 - 2786 (2007/10/03)
Several podophyllotoxin-related cyclolignans, either lacking the lactone ring or the methylenedioxy grouping, have been prepared and evaluated for their immunosuppressive (IMS) activity in the mouse allogeneic MLR in vitro test and in the in vivo techniqu
