The easily available vinyl sulfone 3 showed great potential for new applications in several fields such as organic synthesis and bioconjugate formation. This was demonstrated by performing a systematic assessment of its reactivity in Michael, radical, and cycloaddition reactions. Heteroaryl vinyl sulfone 3 presented excellent output in terms of reactivity and selectivity, proving superior to phenyl vinyl sulfone 1 and with clear advantages over bis-sulfone 2. This behavior might be due to the conformational and orbital control exerted by the tetrazole unit according to DFT calculations. Moreover, some alternative transformations to the Julia-Kocienski olefination on the obtained products are also described.
Tetrazoles. XXXI. Phase-Transfer Reactions of 1-Substituted Tetrazole-5-thiones and Their Derivatives

Alkylation of 1-substituted tetrazole-5-thiones under conditions of phase-transfer catalysis in the two-phase system liquid-liquid proceeds regioselectively at the sulfur atom, regardless of the alkylating agent and phase-transfer catalyst. Phase-transfer oxidation of the 5-alkylthiotetrazoles thus obtained by potassium permanganate is a convenient method for preparation of 5-alkylsulfonyltetrazoles which can be used to synthesize functionally substituted tetrazoles.
