DOI: 10.1016/j.molstruc.2018.06.065
Abstract: Abstract Synthesis and investigation of antifungal activity of ten novel thiazoles derived from tetrahydrothiophen-3-one are presented. Among the derivatives, (E/Z)-2-(2-(dihydrothiophen-3(2H)-ylidene)hydrazinyl)thiazoles 3a-3d and 3h had very strong activity against reference strains of Candida albicans and Candida… read more here.

DOI: 10.1016/j.molstruc.2021.131714
Abstract: Abstract We report here a practical and efficient synthesis of α-aminotrismethylphosphonic acid (ATMP) from (Aminomethyl)phosphonic acid (AMPA) under green conditions using microwave irradiation, via Irani-Moedritzer reaction. The ATMP was characterized by FT-IR, 1H NMR, 13C… read more here.
