Article abstract of DOI:10.1246/cl.1982.1791

The reactions of N-monosubstituted thioureas (1) with β-haloacyl halides (2) were carried out in 5percent NaOH-CH2Cl2 in the presence of a phase transfer catalyst to afford N-thioamido-β-lactams (3 and 5), thioureido acids (4), and 5-hydroxy-2-thiohexahyd
