The title compound, C16H16N2O, a potential antiparasitic agent, crystallizes in the orthorhombic Pca21 space group with unit cell parameters a= 9.912(1) ?, b= 9.035(1) ?, c= 15.681(2) ?. The crystalline structure is stabilized by weak C-H···O and C-H···Cg(π) interactions among neighboring molecules producing an efficient packing with 66.0% of occupied space. The C-H···O hydrogen bond keeps the molecules linked into supramolecular chains propagating along the a axis direction with a graph-set notation C(4), which are reinforced by C-H···Cg(π) interactions. Hirshfeld surface analysis of the intermolecular contacts reveal that the most important contributions for the crystal packing are from H··H (55.2%) and H··C/C··H (27.1%) interactions. Energy framework calculations suggest that the contacts formed between molecules are slightly dispersive in nature.

The synthesis, in vitro antifungal evaluation and SAR studies of 101 compounds of the 4-aryl-, 4-alkyl-, 4-pyridyl or -quinolinyl-4-N-arylamino-1-butenes series and related compounds, are reported here. Active structures showed to inhibit (1,3)-β-D-glucan and mainly chitin synthases, enzymes that catalyze the synthesis of the major fungal cell wall polymers.
An improved and stereoselective route to all-cis-2,6-disubstituted 4-hydroxypiperidines from accessible 4-substituted 4-N-benzylaminobut-1-enes

The reaction between allylmagnesium bromide and imines 5a-l leads to the corresponding 4-substituted 4-N-benzylaminobut-1-enes 6a-1, which were oxidized in a regioselective manner to the alkenylnitrones 7a-l. The intramolecular 1,3-dipolar cycloaddition of these nitrones gave 2-spiroannulated or 2-substituted 6-exo-phenyl-1-aza-7-oxabicyclo[2.2.1]heptanes 8a-j. Reductive cleavage of the N-O bond of the obtained bicycles afforded the diverse substituted 4-hydroxypiperidines 9a-h in good yields. This stereoselective approach allowed the preparation of all-cis-4-hydroxy-6-phenyl-2-nonylpiperidine (9i), a close analogue of dendrobatid frog alkaloid 241D.
