- Lysilactones A-C, three 6H-dibenzo[b,d]pyran-6-one glycosides from Lysimachia clethroides, total synthesis of Lysilactone A
-
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

- Studies of (Pd0-mediated) stille cross-coupling reactions of thiophenestannane with aryl halide derivatives
-
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.

- Course of Aromatisation of 5-Alkyl/aryl-2-bromocyclohex-2-en-3-ol-1-ones to Corresponding 5-Alkyl/arylresorcinols
-
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).
