The synthesis, in vitro evaluation and SAR studies of 67 maleimides and derivatives acting as antifungal agents are reported. A detailed SAR study supported by theoretical calculations led us to determine that: an intact maleimido ring appears to be necessary for a strong antifungal activity, dissimilarly affected by the substituents in positions 2 and 3. The best activities were shown by 2,3-nonsubstituted

Primary aliphaticcarboxylicacids were treated with N-iodosuccinimide (NIS) in 1,2-dichloroethane to form the corresponding alkyl iodides under warming conditions. Based on these results, those aliphaticcarboxylicacids were treated with NIS, followed by the reaction with K2CO3 to give the corresponding N-alkylsuccinimides in good yields in one pot. Moreover, those aliphaticcarboxylicacids were treated

An electrochemical multicomponent reaction (e-MCR) enables highly efficient and selective C–H tetrazolation of alkyl arenes, and vicinal azidotetrazolation of alkenes, with readily available acetonitrile and azidotrimethylsilane.

The triflic acid-mediated endocyclic N-acyliminium ion cyclisation provides a facile synthesis of (di)-benzazocinones. On reduction of the 10-phenyl derivative, an unusually non-polar tertiary alkylamine was obtained.
