    In the title compound, C12H14N2OS, the 1,3-thia­zinane ring displays a screw-boat conformation. In the crystal, pairs of centrosymmetrically related mol­ecules are linked by pairs of N—H⋯O hydrogen bonds into dimers. C—H⋯π inter­actions occur between adjacent dimers

    The title compound, C20H17N3O2S2, crystallizes with two mol­ecules in the asymmetric unit. The pyrrolo­dine rings have envelope conformations in both mol­ecules, the N atoms deviating by 0.574 (3) and 0.612 (2) Å from the mean planes through the other ring atoms. The 1′-methyl and 4′-phenyl groups on the pyrrolidine rings are substituted in equatorial positions. In the crystal, mol­ecules are linked into a three-dimensional network by N—H⋯O, N—H⋯N and C—H⋯O and N—H⋯π hydrogen bonds

    The chemical reactivity of naphthols and their derivatives toward α-cyanocinnamonitriles and ethyl α-cyanocinnamates: A review of synthesis, reactions and applications of naphthopyrano

    Get PDF
    This review deals with synthesis and reactions of some naphthopyrano derivatives and their applications. The main purpose of this review is to present a survey of literatures on the reactivity of naphthols and their derivatives toward α-cyanocinnamonitrile or ethyl α-cyanocinnamate derivatives and the reactions of β-enaminonitriles and β-enaminoesters with different electrophiles followed by nucleophilic reagents. Some of these reactions have been applied successfully to the synthesis of biologically important compounds
