  A facile approach for the syntheses of spirocyclic butenolides through cascade cyclization/oxidative cleavage reactions of (Z)-enynols bearing cyclic substituents at the C-1 position catalyzed by gold under dioxygen atmosphere has been developed. A variety of substituted butenolides was constructed in a regioselective manner from suitably substituted (Z)-2-en-4-yn-1-ols. (Z)-Enynols substituted both

  A NiCl2(PPh3)2/XantPhos catalyzed synthesis of conjugated enynes by the cross-coupling of terminal alkynyl halides with alkenylaluminum reagents at room temperature in DME solvent was developed under mild reaction conditions. The aryls bearing electron-donating or electron-withdrawing groups in alkynylhalides give the corresponding cross-coupling products conjugated enynes in good to excellent isolated

• A new method for the construction of the pyrrole ring by the carbonylcobalt-catalyzed reaction of trimethylsilyl cyanide with acetylenes. Its scope and limitations

  The carbonylcobalt-catalyzed reaction of acetylenes with trimethylsilyl cyanide (1) to give 5-amino-1H-pyrrole-2-carbonitriles is described. Reaction of the symmetric internal acetylenes, 4-octyne (2a) and 2,9-dimethyl-5-decyne (2b), with 1 in the presence of a cobalt complex gave 3a and 3b, respectively, in high yield. From unsymmetric acetylenes were obtained mixtures of regioisomeric pyrroles. The regioisomeric ratio depended on the substitution pattern of the acetylenes and on the kind of substituents possessed by the acetylenes. In the case of the internal unsymmetric acetylenes, 2c-2f, isomers in which the bulkier of the two substituents appeared at the 4-position of the pyrrole ring were obtained as the main products. However, the reaction of internal acetylenes bearing an ester group (2g and 2h) gave a reversed selectively. In case of the terminal acetylenes, 1-octyne (2k), 21, and 2m, isomers in which the alkyl group was located at the 3-position of the pyrrole ring were obtained highly selectively. A new cobalt complex (8), prepared by the reaction of CO2(CO)8 with excess 1, catalyzed the formation of pyrrole 3a from 2a and 1. The stoichiometric reaction of complex 8 with 2a also gave 3a in a good yield.
