studies have demonstrated that functionalized α,α‐diaminoacids ( 1 ) display excellent activity when evaluated in the maximal electroshock seizure (MES) test in mice. The synthesis and pharmacological evaluation of 14 select analogues within this series of compounds are detailed. Included in this survey were 10 N ‐acyl derivatives in which the basic C(α) N ‐group in 1 was replaced by a neutral N ‐substituent
N-(4-Amino-2-butynyl)imides are prepared from N-propargylimides, paraformaldehyde and the appropriate secondary amine. The compounds are useful as stimulants or depressants of the central nervous system.
Abstract (C6F5)3Sb has been found to react with interhalogens and halo-pseudohalogens, IX(X = Cl, Br, N3 and NCO), pseudohalogen (SCN), and elemental sulphur to give oxidative addition products (I–VI). (C6F5)3SbS(VI) may also be prepared by the reaction of (C6F5)3SbCl2 with H2S. Metathetical reactions of (C6F5)3SbCl2 with appropriate metallic salts yield covalent pentacoordinate disubstituted products
