Preparation of the dihydrotriazole from ( )-crotonate and phenyl azide, which was unsuccessful under normal conditions74, was achieved under high pressure, although the a-amino diazo compound was the prevalent product78. IV-Aryl succinimides were suitable substrates for... 

The above directions are based upon the methods of Hoogewerff and Van Doip, as modified by Holm and by Hale and Honan. -Alanine has also been prepared by the action of h3q)obromite upon succinimide and hydrolysis of the resulting /3-ureidopropionic acid by the action of ammonia upon /3-iodo-propionic acid by the hydrolysis of methyl carbomethoxy-/8-aminopropionate, obtained by the action of sodiiun methoxide on succinbromimide by the reduction of 3-nitrosopropionic acid by heating ethyl acrylate with alcoholic ammonia from succinyl-glycine ester by the azide synthesis and by the action of liquid ammonia upon methyl acrylate. ... 

Related methods can be used to prepare 5-hetero-substituted compounds isonitriles with A-halo-succinimides and azide give halo derivatives, aryl isothiocyanates with azide give the 5-thiols, ° which can be converted into 5-unsubstituted tetrazoles by oxidation with hydrogen peroxide or chromium trioxide. ...

Addition of hydrazoic acid to the D-ribose derived enal (25) led to a mixture of epimeric azides (26) which were separately converted into N-benzoyl-L-ristosamine (27) and /V-benzoyl-L-acosamine (28) (Scheme 8). 2,3-Dideoxy-3-amino-nucleosides synthesized from a sugar enal derivative, are covered in Chapter 20. The 5-amino-5-deoxy-L-taluronic acid derivative (30) was obtained by addition of succinimide anion to the nitro-olefin (29) followed by ozonolysis, whereas the D-allo-derivative (31) was obtained when the nucleophile was a sulphonamide anion (Scheme 9). ... 

In recent years, activated esters have become increasingly important in polymer chemistry therefore, it is not surprising that they are also represented in the field of surface modification. In one example, Lin et al. used silica oxide-coated Fc304, where amine functionalities could be attached simply by adding 3-aminopropyltrimethoxysilane (Scheme 23) [44]. The amine was introduced by a disuccinimide, whereby one succinimide reacted with the surface-bonded amine and the other remained accessible for subsequent reaction with 3-azidopropane amine. As described before, the introduced azide could then be used for copper-catalyzed azide-alkyne Huisgen cycloaddition to obtain sugar-coated iron nanoparticles.
