  A convenient two-step one-pot electrochemical synthesis of novel 8-amino-1,4-benzoxazine derivatives possessing anti-stress oxidative properties

  摘要：

  Using (3,4-hydroxy-2-methoxyphenyl) (phenyl) methanone as the starting material, the reaction of the electrogenerated 3,4-quinone with amino alcohols leads to the transient 1,4-benzoxazin-8-one species. The latter can undergo a subsequent addition reaction of an amine at the 8-position affording, after electrochemical reduction, novel 8-amino-1,4-benzoxazine derivatives. The entire sequence can be conducted in one-pot, without isolation of intermediates. (C),1998 Elsevier Science Ltd. All rights reserved.

• Synthesis and in Vitro Evaluation of New 8-Amino-1,4-benzoxazine Derivatives as Neuroprotective Antioxidants

  A series of new 8-amino-1,4-benzoxazine derivatives 5a-o was synthesized and examined for their intrinsic cytotoxicity and their capacity to inhibit oxidative stress-mediated neuronal degeneration in neuronal cell cultures. In particular, substituent effects at the 3- and 8-positions of the 1,4-benzoxazine ring were investigated by in vitro evaluation.. In this aim, 3-alkyl substituents seemed to be essential for efficient neuroprotective activity. Furthermore, within the subseries of substituted S-alkyl benzoxazines, the most active derivatives were those bearing an 8-benzylamino substituent. From the combined results of both toxicity and neuroprotection expressed in terms of the safety index, 8-benzylamino-substituted-3-alkyl-1,4-benzoxazines were identified as the most promising compounds, owing to their potent neuroprotective activity without the manifestation of intrinsic cytotoxicity.
