Intramolecular 5-endo-trig aminomercuration of β-hydroxy-γ- alkenylamines: Efficient route to a pyrrolidine ring and its application for the synthesis of (+)-castanospermine and analogues

Karanjule, Narayan S.,Markad, Shankar D.,Shinde, Vaishali S.,Dhavale, Dilip D.

, p. 4667 - 4670 (2007/10/03)

The intramolecular aminomercuration reaction of sugar-derived β-hydroxy-γ-alkenylamines 8a-c undergoes 5-endo-trig cyclization in high yield. The sugar-substituted pyrrolidines thus obtained were elaborated to the synthesis of polyhydroxylated indolizidin
