The synthesis and some chemical reactions of a5a-methyl 2H-naphtho[1,8-bc]furan
Burns,Taylor,Rodrigo
, p. 42 - 50 (2007/10/02)
A synthesis of the tricycle 19 has been completed in 14% overall yield from guaiacol. Several chemical transformations of this compound including its reduction to an octahydro naphtho[1,8-bc]furan and conversion to the hitherto unknown azuleno[8,1-bc]furan ring system are described.
Electron Impact Mass Spectrometry of Some 2,3-Dihydro-1-benzofuran-3-acetic Acids
Bravo, Pierfrancesco,Ticozzi, Calimero,Daolio, Sergio,Traldi, Pietro,Vecchi, Enrico
, p. 53 - 57 (2007/10/02)
The mass spectrometric behaviour of four 2,3-dihydro-1-benzofuran-3-acetic acids has been studied in detail with the aid of exact mass measurements, linked scans, collisionally activated decomposition, mass analysed ion kinetic energy spectra and labelling experiments.Unusual fragmentation pathways are emphasized for which mechanisms are proposed.
OXYGEN HETEROCYCLES BY SULPHUR YLIDE ANNULATION: 2,3-DIHYDRO-BENZOFURAN-3-ACETIC ACIDS FROM ortho-HYDROXYBENZALACETIC ACID METHYL ESTERS AND DIMETHYLSULPHOXONIUM METHYLIDE
Bravo, Pierfrancesco,Gentile, Anna,Ticozzi, Calimero
, p. 89 - 92 (2007/10/02)
Several 2,3-dihydro-benzofuran-3-acetic acids have been synthesized from ortho-hydroxybenzalacetic acid methyl esters and dimethylsulphoxonium methylide by an annulation reaction.
