For Research Use Only. WebButynyl intermediate 7 is prepared from 2-(benzyloxy)-5-deoxyascorbic acid (15) by iodination (I2, PPh3, Imd), iodo substitution with lithium acetylide ethylenediamine complex (LiAEDA, HMPA, -5 degrees C), and benzyl group cleavage (Ac2O, Pyr, BCl3). The utility of this synthetic method was demonstrated by the synthesis of analogues 10e-k.
Webterminal acetylenes.7 The formation of monolithium acetylide is often complicated by the production of dilithium acetylide.8 9 The reagent may be formed in liquid ammonia, which serves to stabilize the monoanion. Other amines, such as ethylenediamine, may be similarly added as a complexing agent.10 However, it is often desirable to prepare the more
