متن کاملCriss-cross cycloadditions on ketazines derived from alicyclic ketones.
The reactivity of alicyclic ketazines in criss-cross cycloadditions was investigated. They react with potassium cyanate and ammonium thiocyanate in the presence of acetic acid to form spirocyclic perhydro[1,2,4]triazolo[1,2-alpha][1,2,4]triazole-1,5-diones and perhydro[1,2,4]triazolo[1,2-alpha][1,2,4]triazole-1,5-dithiones, respectively, in relatively high yields.
متن کاملThermal Transformations of Some Alicyclic -amino Acid Hydrates
C324 parameters a1 = 10.534(2), a2 = 11.683(2), a3 = 20.407(4)Å, 2 = 93.33(3). When lowering the temperature from 293 K, a strong attenuation of certain ultrasonic resonances occurs reaching a maximum at 288.4 K. Below this temperature the attenuation of ultrasonic waves, in which the elastic constants c11, c22, c12 and c66 are involved, is drastically reduced. If the low temperature phase is h...
متن کاملFatty Acids: Natural Alicyclic Structures, Occurrence and Biochemistry
Alicyclic fatty acids occur naturally in plants, especially certain seed oils, and microorganisms, but only rarely in animal tissues, other than the prostaglandins, which are described elsewhere in these web pages, as are the plant jasmonates. Cyclopropane fatty acids are occasionally reported from marine animals, and some at least may be produced by the animals themselves, although others are ...
متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
