Synthesis of chiral 3-substituted phthalides via rhodium(I)-catalyzed crossed alkyne cyclotrimerisation

3-Substituted phthalides were synthesized for the first time by crossed alkyne cyclotrimerisations with Wilkinson's catalyst. Esterification of propiolic acids with chiral propargylic alcohols by either the DCC/DMAP or the Mitsunobu method allows the synt

Furan-2(3H)- and -2(5H)-ones. Part 7. Photochemical behaviour of tetrahydro- and hexahydro-isobenzofuran-1-one systems: A mechanistic and exploratory study

The photoreactivity of two variations of the di-π-rnethane system involving the tetrahydro- and hexahydro-isobenzofuran structures 10 and 11 have been examined and compared with those of β-apolignans 1. The former, 9-phenyl-1,3,4,5,6,7,8,9-octahydronaphtho[2,3-c]furan-1-one 10a and 7-phenyl-1,3,4,7-tetrahydroisobenzofuran-1-one 10b, gave primarily the di-π-methane rearrangement products 18a and 18b, respectively, while the hexahydro substrate, 7-phenyl-1,3,4,5,6,7-hexahydroisobenzofuran-1-one 11, afforded mainly the photoreduced products 21-24. This difference in chemoselectivity is explained in terms of the variant configuration of the phenyl group, an axially orientated one migrating most effectively. A new pathway for the reaction leading to the cyclopropano product 18a or 18b, by way of another cyclopropano derivative 19a or 19b, respectively, is described.

Intra- and Intermolecular Diels-Alder Reactions of Glutaconaldehyde Derivatives

The intramolecular Diels-Alder reaction of the alcohols 10a-d and maleic anhydride gave the cis-fused cycloadducts 12a-d, whereas the esters 13a and 13c prepared from 10a and fumaric acid ethyl or methyl ester monochloride produced trans-fused adducts 14a

Chemistry of Aryloxazolines. Applications to the Synthesis of Lignan Lactone Derivatives

The syntheses of several lignan lactone derivatives using aryloxazolines as the pivotal intermediates have been investigated.Metalations on naphthyloxazolines followed by electrophilic addition gave one of the appropriate substituents, whereas methoxy dis
