AbstractThe structures of 4-methyl-2-chloro-5,6,7,8-tetrahydroquinoline [a = 8.138(2) Å, b = 11.127(4) Å, c = 11.234(2) Å, β = 111.30(2)°, Z = 4, space group P21/c, 4-methyl-2-methoxy-5,6,7,8-tetrahydroquinoline [a = 5.7651(16) Å, b = 8.530(2) Å, c = 10.455(3) Å, α = 73.76(2)°, β = 86.95(2)°, γ = 83.97(2)°, Z = 2, space group P $$\bar 1$$ , 4-methyl-2-(4-chlorophenacyl)-5,6,7,8-tetrahydro-1H-quinolin-2-one [a = 8.873(2) Å, b = 17.137(2) Å, c = 24.515(4) Å, Z = 8, space group Pbn21], and 2-(4-chlorophenyl)-5-methyl-6,7,8,9-tetrahy-drooxazolo[3.2-a]quinolin-10-ylium perchlorate [a = 8.110(6) Å, b = 17.818(7) Å, c = 17.721(5) Å, β = 100.46(4)°, Z = 4, space group P21/c] are studied by single-crystal X-ray diffraction. The structures are solved by direct methods and refined by the full-matrix least-squares procedures in the anisotropic approximation to R = 0.0581, 0.0667, 0.0830, and 0.0607, respectively.
