Nitrogen Reagents

Some other nitrogen compounds are also formed by carbamoylation of glycals using a photochemical regiospecific process which consists of the addition of the amide radical only to C-l [53]. The addition mixture remains complex because of stereoisomers 54 (mainly a) and competitive addition products with acetone such as 55. [Pg.57]

Most syntheses of nitrogen heterocycles involve substitution and/or condensation reactions of nitrogen nucleophiles with difunctional halides or carbonyl compounds. Common nitrogen reagents are ... [Pg.147]
