  Pd catalyzed cross-coupling reactions of the cycloadducts from 3,5-dibromo-2-pyrone and their synthetic applications towards various mono- and polycyclic compounds

  摘要：

  Bicylolactones from Diels-Alder (D A) cycloadditions of 3,5-dibromo-2-pyrone can undergo various palladium catalyzed cross Coupling reactions to afford a series of alkenyl, alkynyl and aryl bicyclolactones. The resulting coupled products can be readily converted into various 3-OH cyclohexenes via lactone ring openings, while those bearing dienyl units underwent highly diastereoselective D-A cycloadditions with selected dienophiles to furnish multiply functionalized polycarbocycles.

  Flash vacuum pyrolysis at 1000-1100°C of the allyl esters of the three isomeric biphenylcarboxylic acids, of the allyl esters of the 12 biphenyldicarboxylic acids and of the three biphenyldicarboxylic anhydrides gave pyrolysates which were examined by 1H n.m.r. spectroscopy at temperatures below -50°C. In all cases the spectra showed the presence of cyclopent[a]indene and acenaphthylene together with other products. Possible mechanisms for these ring contraction and cyclization processes are discussed and the results of pyrolyses of [2,3-13C2] biphenyl-2,3-dicarboxylic anhydride, and [3,4-13C2]- and (2-2 H1)-biphenyl-3,4-dicarboxylic anhydrides are reported.

  Vinylethylene carbonates have been extensively used to trigger [3 + n] or [5 + n] cycloaddition via the formation of η3-allylic intermediates, while the important [4 + n] cycloaddition has not been explored yet. Here, we report a new strategy to convert vinylethylene carbonates into 4-(trimethylsilyl)but-2-en-1-ols, which can readily undergo [4 + 2] cycloaddition by in situ formation of 1,3-dienes
