experimental part, p. 55 - 57 (2010/11/16)
Synthesis of the glycolurils catalyzed by potassium hydroxide was carried out in 17-75% yield at 40 °C in EtOH under ultrasound irradiation. Compared to the method using stirring, the main advantage of the present procedure is milder conditions and shorter reaction time.

An improved synthesis for the preparation of 3-oxo-1,2,5-thiadiazolidine 1,1-dioxides has been developed. This facile two-step procedure from α-amino acid esters and chlorosulfonyl isocyanate results in excellent yields of products.
