In a article, author is Bannister, R, introduce new discover of the category.
Process research and development for the production of intermediates for the synthesis of carbocyclic nucleosides
The synthesis of [3aR,4S,6R,6aS]-6-amino-N-ethyltetrahydro-2,2-dimethyl -4H-cyclopenta-1,3-dioxole-4-carboxamide, a key single enantiomer intermediate to carbocyclic nucleosides such as adenosine agonists, is reported involving a scalable catalytic osmium tetraoxide dihydroxylation of (-)-2-azabicyclo[2.2.1]hept-5-en-3-one. The acetonide-protected diol [3aS,4R,7S,7aR]-tetrahydro-2,2-dimethyl-4,7-methano-1,3-dioxolo [4,5-c]pyridin-6(3aH)-one is subject to lactam ring opening with anhydrous ethylamine to give the carbocyclic key intermediate, The rate of this known reaction, carried out in a pressure vessel, is considerably enhanced by acid catalysis using ethylammonium ion, In addition, the need for a pressure vessel is circumvented by using anhydrous ethylamine with acid catalysis, Alternatively stoichiometric ethylammonium ion in an appropriate cosolvent can be used to form the key intermediate in high yield.
