5-mercaptotetrazoles as synthetic equivalents of nitrogen-contaning functional groups. the case of the organocatalytic enantioselective aza-Michael reaction

Article abstract of DOI:10.1021/ol102892f

5-Mercaptotetrazoles have been identified as useful and versatile Michael donors in enantioselective amine-catalyzed aza-Michael reactions with α,β-unsaturated aldehydes, showing excellent behavior as N-nucleophiles instead of their usual trend to react a
