Reaction of ¿rans-l-Cyclohexyl-2,3~dibenzoylaziridine (25) with Enedione 1.-A solution of 62 mg of enedione 1 in 5 ml of toluene containing 165 mg of aziridine 25 was heated at reflux for 2.75 hr. Concentration and filtration gave 181 mg (80%) of crude solid product. This was recrystallized several times from benzene to yield an analytical sample of adduct 27: mp 175.5-177°; ir (KBr disk) 1765 (m), 1720 (s), 1675 (s), 1660 (s), 1230 (s) cm-1; nmr (CDC1.) 8 0.5-2.0 (m, 10 H, CH2), 1.12 (s, 3 H, CHa), 1.20 (s, 3 H, CHS), 2.28-2.80 [broad, 1 H, C(1)H of cyclohexyl], 3.
The present paper reviews the centipede species of the genus Bothropolys Wood, 1862 (Lithobiomorpha: Lithobiidae) of the Chinese fauna, including two species recorded from China for the first time. Diagnoses of the genus and the species, detailed account on species distribution and a key to the Chinese Bothropolys species are included.
Aus dem Brom‐pentacyclononanon‐ketal (II) erhält man über den tert.‐Butylperester bei der Zersetzung das Decarboxylierungsprodukt (I), während die direkte Decarboxylierung in Gegenwart von Cu‐Bronze zum Umlagerungsprodukt (III) führt.
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.
