ABSTRACT
Ishiguro and Sugawara (1884) in their 1980 monograph on tobacco smoke components listed a total of seventy-two amides, imides, and lactams (forty-nine amides, seven imides, sixteen lactams) [see Table I-15 in (1884)]. The reference for all but two of the compounds listed (formamide, urethane) was Schumacher et al. (3553). Several amides, imides, and lactams were listed by Ishiguro and Sugawara in other tables, for example, asparagine and glutamine under amino acids [Table I-19 in (1884)], cotinine and norcotinine under alkaloids, caffeine under N-polycyclics (excluding alkaloids).
