Substituted five-membered cyclic nitrones (pyrroline N-oxides) have been obtained in good to high yields from tertiary γ-nitro ketones and nitriles employing aluminium amalgam as a reducing agent in moist diethyl ether or THF. Attempts to obtain cyc

Sulfur-substituted methylmercury compounds [Hg(CH2SR)2](1a, R = Me; 1b, R = Ph) react with aluminium amalgam in refluxing toluene with transmetallation to give homoleptic tris(thiomethyl)aluminium complexes [Al(CH2SR)3](2a, R = Me; 2b, R = Ph) (degre

The titled triazine can be alkylated with LDA and a variety of alkyl halides: subsequent reduction with aluminium amalgam cleaves the naphthotriazine moiety to afford substituted α amino acids in excellent overall yields; the sequence defines a nove
