چکیده
In the title compound, C(13)H(11)ClN(2)O(3), the nine-membered bicycle includes an oxime group having the C=N group in an E configuration. The isoxazole ring is almost planar [r.m.s. deviation = 0.0056 Å]; the dihedral angle between the isoxazole and 4-chloro-phenyl ring is 75.60 (5)°. In the crystal, inter-molecular O-H⋯N(isoxazole) hydrogen bonds give rise to chains running along the b axis.

In the title compound, C(28)H(21)ClN(2)O(3), the quinoline ring system is essentially planar with a maximum deviation of 0.0436 (17) Å. The isoxazole and cyclo-hexane rings adopt envelope conformations. The isoxazole ring is almost orthogonal to both the quinoline ring system and the cyclo-hexane ring, making dihedral angles of 85.75 (8) and 81.46 (9) °, respectively. The O atom deviates signif...
متن کاملSynthesis and Fungicidal Activities of 4,5-Dihydro-7H-pyrano[3,4-c]isoxazole Derivatives.
4,5-Dihydro-7H-pyrano[3,4-c]isoxazoles (II and III) with an o-chlorophenyl or p-chlorophenyl group at C-7 were synthesized and the effect of substitution at C-3 of II and III on fungicidal activity was investigated in vivo. When the substituent at C-3 of II and III was CH2Br, CH=NOMe, CH=NOEt or CH=NO-allyl, the fungicidal effect was significant and selectively high on wheat leaf rust and barle...
