Article abstract of DOI:10.1055/s-1992-26197

CH-Acidic isothioureas 1 react with lactam acetals 2 at the unsubstituted N-atom as well as at the acidic S-methylene group giving 4-(ω-aminoalkyl)thiazoles 6. The latter are further transformed to 4-(ω-lactamiminoalkyl)thiazoles 8, if lactim ethers 3 are used in reactions with isothioureas 1.
