Повний текст джерелаPerfluoroketene dithioacetals are simple and highly versatile building-blocks for the synthesis of various fluorinated acyclic and heterocyclic compounds. Efficient and straightforward transformation of a,b-unsaturated g-lactones into 2,2,2-trifluoroethyl substituted γ-lactams and pyridazin-3-ones was performed, starting from a variety of primary amines or hydrazines and perfluoroketene dithioacetatals. The structures of all new compounds were ascribed using NMR (19F, 1H, 13C), IR, MS data and X-ray diffraction analysis. The possible mechanisms for the formation of γ-lactams and pyridazin-3-ones are also presented. The reactions of N-monosubstituted polyfluorothioamides with alkyllithium reagents were studied. In the case of N,N-disubstituted perfluorothioamides N,S-acetals were obtained. Some chemical properties of perfluoroketene-N,S-acetals, including oxidation and chlorination reactions, were investigated. Oxidation reaction of perfluoroketene-N,S-acetals with t-butylhydroperoxide led to a formation of a-hydroperfluoroamides. Chlorination of perfluoroketene-N,S-acetals with sulfuryl chloride gave a-chloroperfluoroamides; this method proved to be a new approach in the synthesis of polyfluorinated a-chloro optically active compounds. The possible mechanisms for these transformations are discussed

This thesis addresses a novel [6+3] cycloaddition of 2-oxyallyl cation and fulveneketene acetal. The new cycloaddition provides an efficient synthesis of indandiones and the reaction is relatively insensitive to the steric bulk of the cation substituents. Tandem [6+3] cycloaddition-alkylation products were also observed in the reactions when two equivalents of 2-oxy- allyl cation were employed. In addition, reactions of various fulvene analogues were also investigated. The results were consistent with the concept that the high-order cycloaddition scould be enhanced by increasing the electron density onthe fulvenes. Other subjects, including the [6+4] cycloaddition of fulveneketene acetal and α-pyrones as well as synthetic applications to some 4-azulenols, were also studied in this thesis.

1.Studies in Synthesis of C-1 Substituted Fulvenes via the Oxidation-Addition of Haloacetyl Halide to fulveneketene Acetal. In contrast to the [2+2] cycloaddition of fulvenes and ketenes, fulveneketene acetal, 2-chloropentadienylidene-1,3-dioxalane, reacts with a-halo acyl halides to give various C-1 substituted fulvene. Herein we describe the first example of oxidative-addition of a-chloroacetyl chloride to fulveneketene acetal, and formal synthesis of the carbocyclic analogs of Captopril. 2.Traceless Solid-Phase Synthesis of Cyclopenta[c]quinolines and Cyclopenta[c]chromenes via Hetero [6+3] Cycloadditions of Fulvene. A Facile Approach to the 11-Heterosteroids Framework. The hetero [6+3] cycloaddition of fulvenes to benzoquinones and indoanilines provides an efficient route to the synthesis cyclopenta[c]-4H-chromen-8-ol, benzo[d]cyclopenta[e]-3H-3-azin-8-ol and other 11-hetero steroids. The structure of the cyclopenta[c]chromene skeleton was confirmed by the X-ray structure analysis of the p-bromobenzoate of 109. The traceless solid-phase synthesis of the scaldfold, consist of 110 examples, was achieved by the reaction of benzoquinones or iodoanilines with aminofulvene resin 140 which was prepared from polystyrene amino resin 138 via 2-step reaction.
