Azido-phenylselenylation

The tertiary system DIB-sodium azide-diphenyl diselenide was efficient for the azido-phenylselenylation of double bonds. The reaction proceeded with complete... [Pg.39]

Because of the presence of a strong oxidant, these conditions of azido-phenylselenylation did not give satisfactory yields when oxidatively cleav-... [Pg.165]

Addition of phenylselenyl azide to glycals under free radicai conditions [PhSeSeHi, NaNs, (AcO)2lPh] leads to phenyl 2-azido-2-deoxy-l-seleno-glycosides (Vol. 27, p.l32). Further examples have now been published, and the use of the products as glycosyl donors investigated. Notably, however, under polar reaction conditions, 2-phenylselenyl-2-deoxy-glycosyl azides can be formed, as exemplified in Scheme 12. ... [Pg.146]

Azidophenylselenylation of glycals has generated 2-azido-l,2-dideoxy-l-C-phenylselenyl compoimds, and a 4-deoxy-4-C-selenyl derivative has been used in the synthesis of disaccharides with Se in the interglycosidic linkage. A... [Pg.220]
