By using hydroazoic acid (HN3) with triphenyl phosphine and ethylazodicarbo-xylate, vitamin D3 and epi-vitamin D3 were converted to the 3a and 30 azides respectively [scheme (29)]. Reduction with LiAlH4 produced the amino analogs ... [Pg.44]

The Schmidt reaction between hydroazoic acid and aldehyde often gives formamide. However, the reaction with benzaldehyde produces both benzonitrile and formanilide, with the yields varying from 70% and 13% to 5% and 50%, respectively, when the ratio of sulfuric acid/benzaldehyde changes from 0.72 to 5.4. ... [Pg.2504]
