    When serendipity knocks on the door: Synthesis and Physicochemical Characterization of 7-Chloro-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidin-5-one 

    Carmona-Vargas, Christian C.; Ellena, Javier; D’Vries, Richard F.; Chaur, Manuel N. (Sociedade Brasileira de Quimica, 2019-03-19)
    Herein, we present the serendipitous obtaining of 7-chloro-2,3-dihydro-5H-thiazolo [3,2-a]pyrimidin-5-one in 40% yield by using POCl3 and a thiobarbituric acid derivative. The thiazolopyrimidine derivative was characterized ...

    Avoiding irreversible 5-fluorocytosine hydration: Via supramolecular synthesis of pharmaceutical cocrystals 

    Souza, Matheus S.; Diniz, Luan F.; Vogt, Lautaro; Carvalho, Paulo S. Jr.; D’vries, Richard F.; Ellena, Javier (Royal Society of Chemistry, 2018-07-27)
    The antimetabolite 5-fluorocytosine (5-FC) was used to form pharmaceutical cocrystals in order to modulate its poor physicochemical stability in humid environments, which leads to the irreversible incorporation of a water ...

    Order-disorder phase transition induced by proton transfer in a co-crystal of 2,4-dichlorobenzoic acid and trimethylamine: N -oxide 

    D'vries, Richard F.; Moreno Fuquen, Rodolfo; Camps, Ihosvany; Ayala, Alejandro Pedro; Kennedy, Alan R.; Reinheimer, Eric W.; Ellena, Javier (Royal Society of Chemistry, 2017-06-05)
    A crystalline binary adduct between trimethylamine N-oxide (TMANO) and 2,4-dichlorobenzoic acid (2,4-DCBA) molecules was obtained by slow evaporation from acetonitrile. The obtained molecular complex is formed by a racemic ...
