“…Treatment of the dibromide with potassium ieri-butoxide produced an azanortricyclene 68. Similarly, bromination of 69, also Other protons 4.12 s 3.52 m 6.27 m 6.50 q 1.78 AB, J = 9 Hz 6 Reference 25. c Reference 48. a Reference 28.e Satisfactory analytical data (±0.37%) for C, H, and N were obtained for all new compounds in the table except that.54 and 56 were analyzed for Br instead of N, and 49 was not analyzed except in mixture with 48. tricyclenes, no protons attached to unsaturated carbon are indicated and the characteristic apparent singlet for bridge CHBr appears at 4.5-4.8 ppm. The only previous examples of this ring system are the unstable parent heterocycle and its methiodide.…”

Newly developed sulfonyl chloride-based regioselective
chlorothiolation
of alkenes has been disclosed; the reaction is compatible with a variety
of functional groups and can be scaled up to the gram scale with no
loss in yield. The employment of readily available reactants, mild
reaction conditions, and high regioselectivity makes this process
very practical. Mechanistic studies revealed a possible free radical
reaction pathway.
“…In the corresponding reaction of the monosubstituted TosMIC Scheme III. Rationale for the Formation of 2-Imidazolines (4) and Imidazoles (3 and 7) from Aldimines (2) using TosMIC (1) and Analogues (6)0 II, 7d (82%) and 7e (75%), respectively]. To solve this seeming inconsistency, it should be realized that for R3 = Ph or Me the conversion 20 -*• 21 (Scheme III) is blocked.…”
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.
