摘要：
The structures of 4-methyl-2-chloro-5,6,7,8-tetrahydroquinoline [a = 8.138(2) Angstrom, b = 11. 127(4) Angstrom, c = 11.234(2)Angstrom, beta = 111.30(2)degrees, Z = 4, space grou P2(1)/c, 4-methyl-2-methoxy-5,6,7,8- tetrahydroquinoline [a = 5.7651(16) Angstrom, b = 8.530(2) Angstrom, c = 10.455(3) Angstrom, alpha = 73.76(2)degrees, beta = 86.95(2)degrees, gamma = 83.97(2)degrees, Z = 2, space group P (1) over bar, 4-methyl-2-(4-chlorophenacyl)-5,6,7,8-tetrahydro-1H-quinolin-2-one [a = 8.873(2) Angstrom, b = 17.137(2) Angstrom, c = 24.515(4) Angstrom, Z = 8, space group Pbn2(1)], and 2-(4-chlorophenyl)-5-methyl-6,7,8,9-tetrahydrooxazolo[3.2-a]quinolin-10-ylium perchlorate [a = 8.110(6) Angstrom, b = 17.818(7) Angstrom, c = 17.721(5) Angstrom, P = 100.46(4)degrees, Z = 4, space group P2(1)/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.
