The Armed-Disarmed Concept

Transfer of the Armed-Disarmed Concept to Thioglycoside Glycosylation... [Pg.179]

The armed-disarmed concept is tranferrable to having thioglycosides both as donors and acceptors91,92 (Scheme 9). Anomeric activation can, in favorable instances, also be used for this purpose93 (Scheme 10). [Pg.198]

The third concept is programmed glycosylation based on tuning the reactivity of various glycosyl donors (73). This concept is rather similar to the armed-disarmed concept in that both make use of the distinct reactivity of differently protected glycosyl donors. However, the programmed glycosylation... [Pg.68]

The armed-disarmed concept, although discovered with 0-pentenyl glycosides, has been found to be applicable to many other classes of glycosides such as thioglycosides [6], selenoglycosides [39], fluorides [40], phosphoroamidates [41], substituted thioformimidates [42], glycals [21], y-benzoxazolyl (SBox), and 5-thiazolinyl (STaz) [43, 44]. [Pg.133]

An elegant extension of the "armed"/"disarmed" concept is illustrated in Scheme 2 which shows the "disarmed" glycosylating agent (3) used, after debenzoylation and benzylating, in a glycosylation capacity to produce the trimer (4). ... [Pg.59]
