Twenty novel cinnamamide derivatives were designed and synthesized using as lead compound pyrimorph, whose morpholine moiety was replaced by β-phenylethylamine. All the compounds were characterized by their spectroscopic data. The fungicidal and insecticidal activities were also evaluated. The preliminary results showed that all the title compounds had certain fungicidal activities against seve...

In the title compound, C(16)H(17)NO(4)S(2), the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.070 (1) Å, and the morpholine ring adopts a chair conformation; the bond-angle sum for its N atom is 357.9°. The dihedral angle between the the 2H-chromene ring and the best plane through the morpholine ring is 89.09 (6)°. An intra-molecular C-H⋯S hydrogen bond occurs. In the ...

The morpholine and piperazine with their remarkable physical and biochemical properties are popular heterocycles in organic and medicinal chemistry used in rational property design. However, in the majority of cases these rings are added to an existing molecule in a building block approach thus limiting their substitution pattern and diversity. Here we introduce a versatile de novo synthesis of...

The synthesis of the uncommon dihydropyrazinone ring was accomplished by a two-step one pot process taking advantage of the ring rearrangement of N-acylated morpholine acetal derived from serine under acidic treatment in the presence of 2,6-lutidine. The mechanism involves an N-acyl iminium intermediate resulting from morpholine acetal ring opening, which occurs after a nucleophilic attack of t...

The title compound, C(22)H(20)N(2)O(2), was synthesized via a multicomponent reaction using naphthalen-2-ol, morpholine and 4-formyl-benzonitrile. The dihedral angle between the naphthalene ring system and the benzene ring is 81.25 (10)°. The morpholine ring adopts a chair conformation. The mol-ecular conformation is stabilized by intra-molecular O-H⋯N and C-H⋯O hydrogen bonds. In the crystal, ...

In the title compound, C15H14BrNO3S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.034 (2) Å, and the morpholine ring adopts a chair conformation. The dihedral angle between best plane through the 2H-chromene ring system and the morpholine ring is 86.32 (9)°. Intra-molecular C-H⋯S hydrogen bonds are observed. In the crystal, inversion-related C-H⋯S and C-H⋯O inter...
