(Lycaon pictus) urine and feces. Hexanal, octanal, nonanal, acetic acid, benzaldehyde, acetophenone, dodecanal, phenylethyl alcohol, phenol, 2-piperidone, and indole were identified in the MF of lions and the urine of African wild dogs44. 2,5-dimethylpyrazine, one of the characteristic ...
The results confirmed that using 40 mg of Bent-Gu-CD, the model reaction, reaction of benzaldehyde, dimedone and urea, proceeded to give 100% conversion and yield after 15 min. Next, the substrate scope was examined for the synthesis of octahydroquinazolinones (Table 1). As tabulated, the ...
Of cardinal importance were the first syntheses of organic compounds, namely, oxalic acid and urea, by F. Wôhler in 1824 and 1828. Attempts to synthesize analogues of complex natural compounds in the mid-19th century, when a unified theory on the structure of organic compounds did not exist...
