Highly diastereoselective addition of trimethylsilyl cyanide to chiral hydrazones in the presence of Et2AlCl
Choi, Jun Young,Kim, Yong Hae
, p. 7795 - 7796 (1996)
Chiral hydrazones, synthesized from (S)-1-amino-2-methoxymethylindoline and aliphatic aldehydes, reacted with trimethylsilyl cyanide in the presence of diethylaluminium chloride in CH2Cl2 at -78°C to give chiral α-hydrazinonitriles w
Carbamate derivatives of felbamate as potential anticonvulsant agents
Kung, Ching-Hsin,Kwon, Chul-Hoon
experimental part, p. 498 - 513 (2011/03/19)
Several monocarbamate compounds derived from felbamate were synthesized and 11 target compounds (1, 4, and 6-14) were initially evaluated in mice MES and PTZ models in our laboratory. Carbamate compounds with varying substituents on the oxygen (1-4) gave anticonvulsant activity with a wide range of ED 50 in MES test from 300 mg/kg (4) and compounds with different groups on the nitrogen (5-14) also were quite active in the range of 15 mg/kg (14) to 170.5 mg/kg (6). This suggested that the spatial limitation in the MES model seemed flexible especially on the nitrogen end. All tested compounds showed some activity against mice scPTZ test, but none had the ED50 value 50 mg/kg. Ten selected compounds (1 and 6-14) for subsequent pharmacological evaluation in NIH all gave positive mice MES activity except 8 and 9, which were unexpectedly active in rats after further evaluations. Among the compounds, 1, 8, and 9 advanced to the quantitative study and 1 and 9 provided the highest PI values, 15 and 21, respectively, in the rat oral MES test.
