Ueber die N‐Methylolverbindungen der Säureamide [Erste Abhandlung.]

Abstract: J a f f e lo) stellte aus Krcatin und Kreatinin das Dioxymethylenkreatinin, N(CH,OH) HO-CH,.N=C/ \GO, \N(cH,)-cH,/ her. Ferner ist die sogenannte Methylenhippursaure 11), eine anhydrische Verbindung der Formel CH,-CO C,,H,-CO-N' j , und die entsprechende m-Nitroverbindung beschrieben worden. Schon lange ist es bekannt, dass Chloral, Broiiial and andere halogenhaltige Aldehyde. die befdhigt sind, Glycole ZU bilden, mit Saureamiden zu Verbindungen voni Typus 'cn-0 B-CH(OH)-NH-COR' zusammentreten konnen. Solche S… Show more

“…All new compounds were synthesized via a "one-pot" Tscherniac-Einhorn reaction, 11,12 in a considerably optimized way when compared to previous publications. 2,3 Basically, it consists of a three-compound reaction, which is, therefore, referred to as TsE-3CR (Tscherniac-Einhorn three-compound reaction).…”

“…The first step of the unoptimized synthetic route towards the target compounds (1 or 2) is the condensation of the carbamate (9) with glyoxylic acid monohydrate (10). The condensation product (11) is then used together with a para-substituted phenol derivative (12) as the starting material for the actual Tscherniac-Einhorn reaction. After the recrystallization of the solid product obtained (13), it has to be converted into the target compounds (1 or 2) by stirring it under reflux in acetic anhydride.…”

“…Its comparison with that of the resulting spent solution of 5a revealed only a small difference of 4 nm of the maximum. Thus, it can be assumed that compound (10) or its deprotonated form constitutes the main product of the chemiluminescence reaction of lactone (5a). Therefore, we suggest the following mechanism (Scheme 5) in analogy to Lofthouse et al…”
