Three 6H-dibenzo[b,d]pyran-6-one glycosides named lysilactones A-C (1-3) were isolated from the aerial parts of Lysimachia clethroides. Their structures were elucidated using spectroscopic analysis and chemical evidence. This is the first report of 6H-dib

Regioselective synthesis of 9,10-Dihydro-2,5-Dimethoxyphenanthrene-1,7-diol (1) and 9,10-Dihydro-2,7-Dimethoxyphenanthrene-1,5-diol (2) was achieved using regioselective methylation, Wittig reaction, intramolecular cyclization and hydrogenation as key ste
Studies of (Pd0-mediated) stille cross-coupling reactions of thiophenestannane with aryl halide derivatives

, p. 131 - 143 (2007/10/03)
Stille (arylstannane) conditions used Pd0-mediated cross-coupling reactions for preparation of thiophene/aryl analogs. Different arylhalides were compared when coupled with heterometal (thiophenestannane) system. Comparable yields have now been obtained by Stille (arylstannane) couplings with different reactivity of arylhalides.
Halogenation Using Quaternary Ammonium Polyhalides. IV. Selective Bromination of Phenols by Use of Tetraalkylammonium Tribromides

Reaction of phenols with calculated amounts of benzyltrimethylammonium tribromide or tetrabutylammonium tribromide in dichloromethane-methanol for 0.5-1 h under mild conditions gave, selectively, the objective mono-, di-, or tribromophenols in good yields.

5-Alkyl/aryl-2-bromocyclohex-2-en-3-ol-1-ones on heating undergo aromatisation through dehydrobromination to the corresponding 5-substituted resorcinols.During the course of aromatisation of 2-bromo-5-methylcyclohex-2-en-3-ol-1-one (I) and 5-n-amyl-2-bromocyclohex-2-en-3-ol-1-one (II) a few intermediates have been isolated and characterised as IV, V, VI, VIII and IX.Similar studies on 2-bromo-5-phenylcyclohex-2-en-3-ol-1-one yields two structurally different products, one with no bromine (XI) and the other with bromine in position-2 (XII), besides 5-phenylresorcinol (XIII).
