The silylation of 2-oxa-7,7′-dichloronorcarane has been studied. According to the reagent (Me3SiCl/Li/THF or MeSi3Cl/Mg/HMPT), we observed significant differences in the reactivity, and silyloxabicyclonorcaranes or silylhydrooxepines were obtained. The influence of solvant and experimental ...
The synthesis of 2,8-dioxa-6-thiobicyclo[3.2.1]octanes, substituted by alkyl or phenyl groups in positions 1, 4, or 7, is described. Four synthetic routes are compared: (i) action of sodium sulfide on 2,4-dichloro-1,3-dialkyldioxolanes; (ii) action of sodium sulfide on the ...

Variations of these activities were checked in the transfer cells of the cotyledonary node in the intact or decapitated plant. They were also studied in the shoot apex of both inhibited (G0state) and released cotyledonary buds, during the transitions G1–S orG2–M. The adenylate cyclase ...
The diamine (VII) was obtained as follows: 1°) 2-hydroxy-3-nitro-5,6-diphenylpyrazine (V) + POCl 3 (or PBr 3 ) (or PBr 3 ) 2,3-dichloro-(or dibromo-)-5,6-diphenylpyrazine (VIb) (or VIc) [also VIb + PBr 3 Vlc], 2°) Vlb (or VIc) + NH 3 2,3-diamino-5,6-...
Nous décrivons la synthèse de bis (alkyl-4 phényl) et bis (alkoxy-4 phényl) tétrathiafulvalènes originaux. Certains d'entre eux présentent un polymorphisme dont on a précisé les températures de transition. We report the synthesis of di(4-alkoxyphenyl)- and di(4-alkanoyloxy-phenyl)...
