Iodobenzene catalysed synthesis of spirofurans and benzopyrans by oxidative cyclisation of vinylogous esters.
نویسندگان
چکیده
Vinylogous esters bearing para or meta methoxy benzyl groups undergo oxidative cyclisation with 5-20 mol% iodobenzene and m-CPBA to give spirofuran or benzopyran containing heterocycles. The reaction allows rapid generation of skeletal complexity in good to excellent yields via a novel oxidative cyclisation.

Base catalysed synthesis of thiochromans and azo-linked chromenes using allenylphosphonates.
An efficient base catalysed approach to the synthesis of thiochromans/chromenes from allenylphosphonates (and an allenoate) and substrates having SH/OH and CHO groups at appropriate positions has been developed. Several azo-linked chromenes that are bright red pigments are also synthesized. This methodology involves the domino reactions of Michael addition and subsequent cyclisation by intramol...
متن کاملSynthesis of neopentyl glycol and ethylene glycol esters by fatty acids in the presence of acidic ion exchange resin catalyst
A most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. In this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...
متن کاملPalladium-catalysed cyclisation of alkenols: Synthesis of oxaheterocycles as core intermediates of natural compounds
The study of Pd-catalysed cyclisation reactions of alkenols using different catalytic systems is reported. These transformations affect the stereoselective construction of mono- and/or bicyclic oxaheterocyclic derivatives depending on a starting alkenol. The substrate scope and proposed mechanism of Pd-catalysed cyclisation reactions are also discussed. Moreover, the diastereoselective Pd-catal...
متن کاملStereospecificity in the Au-catalysed cyclisation of monoallylic diols. Synthesis of (+)-isoaltholactone.
We describe a concise synthesis of (+)-isoaltholactone via a Au-catalysed cyclisation of a monoallylic diol to form the tetrahydrofuranyl ring. Analogous cyclisations show that the stereochemical outcome is dictated by the stereochemistry of the diol substrate.
متن کاملA borylative cyclisation towards indole boronic esters.
2-Alkynylaniline borylative cyclisations provide a direct means to access indole 3-boronic esters from simple precursors. The Pd-catalysed cyclisation can be merged with cross-coupling processes in the same reaction vessel, moreover, the products can be exploited in C-N bond forming reactions.
