Calculate Digit Verification of CAS Registry Number 1201680-72:
(9*1)+(8*2)+(7*0)+(6*1)+(5*6)+(4*8)+(3*0)+(2*7)+(1*2)=109

Synthesis of ent-gabosine E from d-mannose by intramolecular nitrone-olefin cycloaddition

Stathakis, Christos I.,Athanatou, Maria N.,Gallos, John K.

, p. 6916 - 6918 (2009)

Intramolecular nitrone-olefin cycloaddition in a mannose template followed by N-O cleavage, quaternization of the resulting amine, and finally oxidative elimination of the amino group affords, after deprotection, ent-gabosine E in enantiomerically pure form.
