“…Nomilin is a limonoid first isolated from the seeds of oranges and lemons (Emerson, 1948). It is bitter (Emerson, 1948,1951 and is reported to be about twice as bitter as limonin (Hashinaga et al, 1977).…”

“…M3 was prepared by adapting the method of Emerson. 36 Melamine (630 g, 5 mmol) and decanoic anhydride (13.1 g, 40 mmol) were placed in a round bottom flask and heated at 150 °C under N 2 for 16 hours. The reaction was cooled, precipitated in ethyl acetate, filtered, and dried to obtain the crude product.…”
A series of triazine-based compounds (M1–M7) have been prepared from 1,3,5-triazine, 2,4,6-triamino-1,3,5-triazine, 2,4-dichloro-6-methoxy-1,3,5-triazine and 2-chloro-4,6-dimethoxy-1,3,5-triazine, and their thermal phase change properties.
“…Limonoids, first reported in 1864 (Emerson, 1948), are a group of chemically related triterpene derivatives found in the Rutaceae and Meliaceae families (Bennett & Hasegawa, 1982;Hashinaga et al, 1990). Nomilin is one of the most prevalent citrus limonoids.…”
The absolute stereochemistry of the title compound, C28H33O9·CHCl3, has been determined by single‐crystal X‐ray diffraction by incorporation of the heavy‐atom‐containing solvent chloroform. The A/B, B/C and C/D ring junctions are all trans‐fused. Five‐membered ring E is equatorially attached to ring D. The crystal structure is stabilized by weak intermolecular C—H⋯O interactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
