  An improved method for the synthesis of a new series of trichloromethyl-β-diketones including 1,1,1-trichloropentan-2,4-dione (2a), 1,1,1-trichloro-3-methylhexan-2,4-dione (2b), 4,4,4-trichloro-1-phenylbutan-1,3-dione (2c), 4,4,4-trichloro-2-methyl-1-phenylbutan-1,3-dione (2d), 2-trichloroacetylcyclohexanone (2e), 4-tert-butylcyclohexanone (2f), 4-tert-butylcycloheptanone (2g), and 4-tert-butylcyclooctanone (2h) is reported. A multinuclear NMR study showed that β-dicarbonyl compounds 2b and 2d–2h are predominantly in the keto form and 2a and 2c are in the enol form. The trichloromethyl-β-diketones react with hydroxylamine hydrochloride leading to three sets of isoxazole derivatives.Key words: acetals, acylation, trichloromethyl-1,3-diketones, 2-trichloroacetylcycloalkanones, isoxazoles, cyclocondensation.

  cyclocondensed with hydroxylamine hydrochloride to afford the 3-aryl-5-hydroxy-5-trihalomethyl-4,5-dihydroisoxazoles 3a-g, 4a-f in good yield. The dehydratation of compounds 3a-g with concentrated sulfuric acid, led the corresponding 3-aryl-5-trichloromethylisoxazoles 5a-g. An alternative one-pot procedure yields 3-aryl-5-trihalomethylisoxazoles 5,6a-g directly by cyclocondesation of 1,2a-g with hydroxylamine

  A series of 13 5-hydroxy-5-trichloromethyl-4,5-dihydroisoxazoles have been synthesized in 78-96% yield by environmentally benign microwave induced techniques involving the cyclocondensation of 4-alkoxy-1,1,1-trichloro-3-alken-2-ones [CCl3C(O)C(R-2)=C(R-1)OR, where R-2=H, alkyl; R-1=H, alkyl, aryl and R=H, alkyl] with hydroxylamine using toluene as solvent. The advantages obtained by the use of microwave irradiation in relation to a classical method were demonstrated. (C) 2002 Elsevier Science Ltd. All rights reserved.

  A series of twelve 5-trihalomethyl-3-arylisoxazoles was synthesized and screened for antibacterial and antifungal activities. The compounds were synthesized from the cyclondensation of 1,1,1-trihalo-4-alkoxy-3-alken-2-ones [CX C-3(O)C(R-2)=C(R-1)OR, where X = Cl and F; R=Me; R-2=H; R-1=H, Me, F, Cl, Br, and NO2] with hydroxylamine hydrochloride through a rapid one-pot reaction via microwave irradiation. Some of the 5-trihalomethyl-3-arylisoxazoles exhibited good in vitro anti-Cryptococcus activity.

  The X-ray diffraction data determined for eight 3-(R-3), 4-(R-4), 4,4-(R-4/R-4') and/or 5-(R-5) 5-hydroxy-4,5-dihydroisoxazoles [where R-3 = Ph, R-4/R-4' = H/H, R-5 = CCl3 (1); R-3 = 4-Br-C6H4, R-4/R-4' = H/H, R-5 = CCl3 (2); R-3 = thien-2-yl, R-4/R-4' = H/H, R-5 = CCl3 (3); R-3 = Ph, R-4 = Ph, R-4' = OH, R-5 = Me (4); R-3 = Me, R-4/R-4' = N-OH, R-5 = Me (5); R-3 = CF3, R-4/R-4' = H/H, R-5 = CMe2CH2OH (6); R-3 = H, R-4 = 4-I-C6H4, R-4' = H, R-5 = 4-I-C6H4 (7): R-3/R-4 = -(CH2)(3)-, R-4' = H, R-5 = CF2CF2H (8);] are discussed. The crystalline structure of compounds 1-3 is described for the first time and crystalline structure of compounds 4-8 has already been described in literature. It was found that the supramolecular auto-organization of 1-8 is characterized by hydrogen bonds invariably involving the hemiacetal hydroxyl group. Compound 5 is the only exception, where the hydroxyl oxime group is the participant in the hydrogen bond. Compounds 4 and 8 present intermolecular contact between the hydroxyl group of the hemiacetal and the nitrogen atom of the 4,5-dihydroisoxazole ring. Compound 7 presents similar interaction, where the hydroxyl contact is with the oxygen atom of the 4,5-dihydroisoxazole ring. Moreover, the crystal structure of compound 6 was stabilized by O-H center dot center dot center dot O interaction between the hydroxyl group of hemiacetal and the hydroxyl group of the alcohol function attached at the 5-position of 4,5-dihydroisoxazole. The crystal structure of compounds 1-3, as described here for the first time, was similar to that of compounds 4 and 7, showing a hydrogen bond O(51)-H(51)center dot center dot center dot N(2) between the hydroxyl group and the nitrogen atom of the isoxazoline ring. This means that the crystal structure of these compounds was governed by hydrogen bonds O-H center dot center dot center dot N, involving the hydroxyl of the hemiacetal group and the nitrogen atom of the 4,5-dihydroisoxazole ring. This interaction is relatively robust, showing a pattern in the crystal packing. Compounds 1-3 also have their crystal stabilized by more weak interactions of type Cl center dot center dot center dot Cl, involving the chlorine atom of the trichloromethyl group.
