Abstract :

Tuberculosis (TB) is a disease which results from infection by Mycobacterium tuberculosis (Mtb) and it has been responsible for the death of almost 30 million of people around the world. In Mexico, on year 2012, about 19,735 new cases of tuberculosis were reported, in which roughly 81% were pulmonary type and 395 were drug resistant occurrences. Due to this cause, it is of great importance to develop new chemotherapeutic agents derived from oxazolines and thiazolines with the purpose of obtaining better results on the activity of anti-TB, with low cytotoxicity and reducing the appearance of resistant strains. The objective of this project is synthetize oxazolines 4 and thiazolines 5 under microwave irradiation (MW), which will reduce the reaction times, the quantity of the reagents and the energy consumption. In order to achieve this goal, it was used triethyl phosphonoacetate 1 with a variety of amino alcohols to obtain the amides 2 and thioamides 3, which later they were treated with K2CO3 and EtOH under MW conditions, followed by the addition of various aromatic aldehydes. In conclusion, oxazolines 4 and thiazolines 5 were successfully obtained with short reaction times, without catalyzer utilization, and with the minimum amount of solvent.
