Propenitrile derivatives. Yamamoto, Yoshikimi; Sako, Taizo; Shioda, Yutaka; Fujii, Shigeo (Ouchi Shinko Chemical Industrial Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 61246159 A2 1 Nov 1986 Showa, 4 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07C149-24. ICS: C07C149-243; C07C149-273.In this article, certain chemicals are used. Some of their cas registry numbers are 5147-80-8 and 107325-25-7 APPLICATION: JP 85-85504 23 Apr 1985. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Propenitrile derivs. (I; R = cyano, CONH2, acyl, alkoxycarbonyl, etc; R1 = alkyl; R2 = alkoxycarbonylalkyl, hydroxyphenylalkyl, etc.), useful as synthetic intermediates for amino acids, are prepd. Thus, a mixt. of (NC)2C:C(SMe)2 0.05, di-Et L-glutamate 0.055, and K2CO3 0.0275 mol in EtOH was stirred at 30° to give 90% I (R = cyano, R1 = Et, R2 = CH2CH2CO2Et). .

Reaction of pyridinium and quinolinium N-imines with ketene thioacetals

Reaction of pyridinium and quinolinium N-imines with ketene thioacetals.Some chemicals with cas registry numbers like 5147-80-8 are also used.

ISSN: 0031-6903. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Reaction of 1-aminopyridinium and 1-aminoquinolinium mesitylenesulfonates (I; R = H, RR = benzo; R1 = H, Me, cyano, etc., R2 = H, Me, H2NCO; X = mesitylenesulfonate) with (MeS)2C:C(CN)2, (MeS)2C:CHNO2, and (MeS)2C:CXSO2C6H4R3-p (R3 = H, Me; X = cyano, EtO2C, Ac) gave N-substituted (1-pyridinio)amides, (1-quinolinio)amide, pyrazolo[1,5-a]pyridines and pyrazolo[1,5-a]quinolines II (R4 = H, Me; R5 = H, Me, H2NCO, cyano, etc.; R6 = O2N, cyano, EtO2C, Ac; R7 = MeS, cyano) in good yield. I also reacted with MeSC(CN):C(CN)SO2Ph to give II (RR = benzo, R4 = R5 = H, R6 = R7 = cyano) in good yield. .
