  Regio- and stereoselective C-10 beta-H functionalization of sinomenine, an economically available natural immunomodulating alkaloid, has been studied, developed and successfully applied to the synthesis of new immunosuppressive sinomenine derivatives in a protecting-free fashion. Regioselective oxidation of sinomenine with (diacetoxylodo)benzene (DIB) in water provided a single stable benzoquinone derivative 4, and subsequent 1,6-conjugated addition of 4 with alcohols, amines, and thiols afforded a new series of C-10 beta-H functionalized sinomenine derivatives stereoselectively. Some derivatives with a newly introduced 10 beta-bezenesulfanyl substituent exhibited much higher TNF-alpha inhibitory potency than their natural parent sinomenine. This work opens a convenient access to novel sinomenine derivatives with medicinal interests. (C) 2012 Elsevier Ltd. All rights reserved.
