Synthesis of enantiomerically pure β-azidoselenides starting from natural terpenes
摘要:
Several unsaturated natural terpenes have been easily converted, in good yields, into the corresponding enantiomerically pure P-azidoselenides by addition of the electrophilic selenium reagent PhSeOTf in the presence of sodium azide. These reactions are stereospecific anti additions, which occur with a Markovnikov orientation. Examples of the synthetic importance of these beta-azidoselenides are also reported.
