Réactivité de spirochromènes et de mérocyanines azahétérocycliques vis‐à‐vis de quelques agents nucléophiles

Abstract: Les spirochromènes azahétérocycliques saturés réagissent avec les agents nucléophiles comme l'eau, l'hydrogène sulfuré et le borohydrure de sodium. Ils subissent alors une ouverture soit de leur partie hétérocyclique azotée, soit de leur partie chroménique, soit des deux simultanément. Quant aux mérocyanines, elles peuvent ětre soit partiellement réduites, soit décomposées par le borohydrure de sodium.

“…89,90 The most useful alkylating agents are those having an excellent leaving group (iodide and p-toluenesulfonate derivatives). [89][90][91][92][93] With less reactive nucleophiles such as bromide, lower yields are obtained (entries 21 and 22). Low molecular weight alkyl halides such as methyl iodide afforded good yields (Table 7, entries 1-16).…”
