The six-membered oxacyclo-hexene ring of the title compound, C(13)H(14)N(2)O(2)S, is fused with the benzene ring and the quarternary C atom lies above the plane of the benzene ring by 0.229 (8) Å, whereas the methine C atom (which bears the acetyl substituent) lies below this plane by 0.595 (8) Å. The oxacyclo-hexene ring is also fused with the sofa-shaped 2,6-diaza-cyclo-hexa-none ring. The me...
The six-membered N-heterocyclic ring of the title compound, C(17)H(15)ClN(2)O, is fused with a methyl-substituted cyclo-hexene ring. The approximately planar nitro-gen-bearing ring (r.m.s. deviation 0.019 Å) is aromatic, and the N atom shows a trigonal-planar coordination; its benzene substituent is aligned at 77.1 (1) °. The cyclo-hexene ring adopts a half-chair conformation. In the crystal, i...
Five of the atoms of the six-membered cyclo-hexene ring of the title compound, C(17)H(20)O(2), are essentially coplanar (r.m.s. deviation = 0.006 Å), with the sixth (the dimethyl-methyl C atom) deviating from the mean plane of the five atoms by 0.610 (2) Å. This plane is nearly perpendicular to the cinnamyl portion, the two planes being aligned at 85.1 (1)°. Two mol-ecules are linked by an O-H⋯...
Aliphatic thiols are in high demand materials chemistry. Herein, a synthesis of thio-derivatives 1-hexene vinylidene dimer is described. The approach, based on hydroalumination reaction with further replacement the organoaluminum function sulfur using thiourea or dimethyl disulfide, provides anti-Markovnikov products, 2-butyloctane-1-thiol 5-(methylsulfanylmethyl)undecane, moderate yields. phos...
In the xanthene ring system in the title compound, C19H18O4, the 4H-pyran ring has a maximum deviation of 0.110 (2) Å from planarity and the cyclo-hexene ring exhibits a puckered conformation [puckering parameters Q T = 0.452 (3) Å, θ = 57.0 (4) and ϕ = 131.7 (4)°]. The cyclo-hexene ring attached to the xanthene system adopts an envelope conformation, with the middle of the three methylene C at...
