Recently I am researching about C-H AMINATION; CROSS-COUPLING REACTIONS; N-ARYLATION SEQUENCE; CENTER-DOT-LICL; ELECTROPHILIC AMINATION; DEPROTOMETALATION-IODINATION; ANTIPROLIFERATIVE ACTIVITY; DEPROTONATIVE METALATION; BOND FUNCTIONALIZATION; HETEROCYCLIC AMINES, Saw an article supported by the Alexander von Humboldt foundationAlexander von Humboldt Foundation. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Bouarfa, S; Grassl, S; Ivanova, M; Langlais, T; Bentabed-Ababsa, G; Lassagne, F; Erb, W; Roisnel, T; Dorcet, V; Knochel, P; Mongin, F. The CAS is 177-11-7. Through research, I have a further understanding and discovery of 1,4-Dioxa-8-azaspiro[4.5]decane. HPLC of Formula: C7H13NO2
Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.
HPLC of Formula: C7H13NO2. About 1,4-Dioxa-8-azaspiro[4.5]decane, If you have any questions, you can contact Bouarfa, S; Grassl, S; Ivanova, M; Langlais, T; Bentabed-Ababsa, G; Lassagne, F; Erb, W; Roisnel, T; Dorcet, V; Knochel, P; Mongin, F or concate me.
