Article abstract of DOI:10.1007/BF00809250

Meldrum's acid (1) reacts with isothiocyanates and LiH as base, yielding after alkylation the ketene-S,N-acetales 3, 4 and 5.Protonation of the lithium-thiolate 2 gives the thioamides 7 with tautomers 8, which can be methylated with diazomethane to 9.From
