Three different substituted thiazoles have been successfully synthesized from readily available propargylic alcohols. Various secondary propargylic alcohols or tertiary propargylic alcohols participated well in the reaction, providing the desired products in good yields. This method provides a flexible and rapid route to substituted thiazoles.

Multi-component reactions for the synthesis of polysubstituted thiazoles from simple chemicals are described. Under metal-free reaction conditions, cheap and easily available ketones, aldehydes, ammonium salt, and elemental sulfur are self-assembled to provide entries to three thiazoles in moderate to good yield with a range of functionalities tolerated.
