摘要

Abstract A series of 2-[bis (alkylthio) methylene]-3-oxo-No-tolylbutanamides 1 have been investigated as nonthiolic and odorless thiol equivalents in thia-Michael addition reactions. The cleavage of compounds 1 is initiated by NaOH in EtOH; the in situ generated thiolate anions undergo facile conjugate addition to α, β-unsaturated carbonyl compounds 2 affording the corresponding β-keto sulfides 3 in very high yields. Meanwhile, 3-oxo-No- ...
