On September 29, 2005, Stead, Darren; O’Brien, Peter; Sanderson, Adam J. published an article.Recommanded Product: tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate The title of the article was Concise Synthesis of (±)-Cytisine via Lithiation of N-Boc-bispidine. And the article contained the following:
(±)-Cytisine (I) has been synthesized in 19% overall yield via a six-step approach from com. available materials. Key features of this new strategy are as follows: (i) initial construction of the bispidine core, (ii) lithiation-transmetalation-allylation of an N-Boc-bispidine, and (iii) a Pd/C-mediated dihydropyridone oxidation-N-debenzylation process. The experimental process involved the reaction of tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate(cas: 227940-70-7).Recommanded Product: tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate
