Preparation of 1,5-disubstituted tetrazoles under phase-transfer conditions

, p. 1428 - 1430 (2007/10/03)
Imidoyl chlorides, obtained by common methods from a wide range of aromatic mono- and diamides, are smoothly converted to the corresponding tetrazoles in high yields by treatment with NaN3 under phase-transfer conditions.
Generation and Reaction of N-(α-Lithioalkyl)tetrazoles
Moody, Christopher J.,Rees, Charles W.,Young, Richard G.
, p. 323 - 327 (2007/10/02)
Treatment of 1-alkyl-4 and 2-alkyl-5-phenyltetrazoles 10 with t-butyllithium in tetrahydrofuran at -78 deg C gives 'dipole-stabilised' α-lithioalkyl derivatives 2 and 3 which are readily converted into the corresponding deuteriated, silylated, alkylated, hydroxymethylated, acylated and carboxylated derivatives 5 and 11, mostly in high yield (Tables 1 and 2).Lithiation of 5-phenyl-2-trimethylsilylmethyltetrazole 10c, prepared in this way, followed by reaction with aldehydes results in Peterson olefination to give 2-alkenyltetrazoles 11g, h in good yield.
Novel regioselective N-alkylations of 5-substituted-2H-tetrazoles
Prhavc,Kobe
, p. 1925 - 1928 (2007/10/02)
Regioselective alkylation of 5-substituted-2H-tetrazoles 1 to 2-alkyl derivatives 3 was achieved via decarboxylative alkylation with alkyl cyanoformates. Lesser selectivity was observed with chloroformates.
