, p. 2895 - 2898 (1994)
The title compounds have been obtained from 5-amino-1,2,3-thiadiazole 6 by methylation and reaction with arenediazonium tetrafluoroborates; their 13C NMR data and X-ray analysis are discussed in terms of two non-equivalent resonance contributors 11A and 11B.
Ag-and Au-catalyzed addition of alcohols to ynimides: β-regioselective carbonylation and production of oxazoles

Metal-catalyzed reactions of ynimides with alcohols to afford β-ketoimides and oxazoles are demonstrated. The triple bond of ynamides is generally activated by mineral acids or metal salts to lead to the regioselective addition of nucleophiles at the α-C-

(Chemical Equation Presented) A novel catalytic system for asymmetric hydrogenation of functionalized ketones has been developed using a Pd/bisphosphine complex as the catalyst in 2,2,2-trifluoroethanol. The reaction exhibits high enantioselectivity, and
Concise synthesis of 1H-pyrazin-2-ones and 2-aminopyrazines

, p. 2031 - 2033 (2007/10/03)
Convenient syntheses of 1H-pyrazin-2-ones and 2-aminopyrazines are described. By coupling Boc-protected amino acids with α-amino ketones or with amino alcohols and subsequent oxidation, 1H-pyrazin-2-ones were obtained. Transformation into the corresponding pyrazine triflates and substitution with primary or secondary amines led to 2-aminopyrazines. Since these syntheses take advantage of the use of readily available starting materials (e.g., amino acids, aminoalcohols and amines) a variety of the entitled structures can be obtained in few, high yielding steps.

Novel imidazole compounds, pesticidal compositions and methods of using them, and their preparation are described. The compounds have the formula STR1 in which X is oxygen or sulphur, R3 is hydrogen, alkyl, alkenyl or optionally substituted alkylthio, alkenylthio, aralkylthio, alkoxyalkyl or alkylthioalkyl, R4 is alkyl or cycloalkyl, and R1 and R2 are each lower alkyl or alkenyl, R1 is lower alkyl and R2 is alkoxyalkyl or haloalkyl, or R1 and R2 together with the nitrogen atom to which they are attached, form an optionally substituted heterocyclic ring; and salts thereof. Novel compounds are of particular value against insects e.g. aphids, and against other pests, e.g. acarids.
