Synthesis of 3-alkenylamines, 4-alkenylamines and 3-allenylamines via a transamination procedure
摘要:
3-Alkenylamines, 4-alkenylamines and 3-allenylamines were synthesized conveniently by potassium t-butoxide induced transamination of alpha-vinylaldimines, alpha-allylaldimines or alpha-allenylaldimines followed by hydrolysis with aqueous oxalic acid. (C) 1997 Elsevier Science Ltd.

2-Alkylamino-substituted-1,4-benzoxazine derivatives, a new class of potential neuroprotective agents, were synthesized and examined for their intrinsic cytotoxicity and their capacity to inhibit oxidative stress-mediated neuronal degeneration in vitro. Through structure-activity relationship studies, the 3,3-diphenyl-substituted-1,4-benzoxazine derivative 31 was identified as the optimal candidate, owing to its potent neuroprotective activity, without the manifestation of intrinsic cytotoxicity. Accordingly, 31 proved to be effective in an animal model of excitotoxic lesions in newborn mice.
