Synthesis of 2-(Polyhydroxy)alkyl- and 2-(6-Adenosinyl)benzisoselenazol-3(2H)-ones
摘要:
A convenient method for synthesis of benzisoselenazol-3(2H)-ones substituted on the nitrogen atom with (polyhydroxy)alkyl or adenosinyl group is presented. It is based on the tandem acylationselenenylation of primary amino group in aminopolyols or adenosine with 2-(chloroseleno)benzoyl chloride. The process is selective because oxygen nucleophiles (hydroxy groups) remained unreactive in the reaction conditions.
