Owing to tremendous technological advances, computational chemistry has evolved into a powerful tool for the development of reactions used to construct complex molecules. Computational models that allow chemists to predict the selectivity of a reaction are highly sought after because they enable rapid and efficient construction of intricate scaffolds. The first part of the presentation will detail computational studies onthe reaction of strained alkynes and arynes with oxadiazinones and the application of this reaction to the synthesis of non-symmetric polycyclic aromatic hydrocarbons. Several mechanistic aspects of the transformation were interrogated using density functional theory DFT calculations, including the differing reactivities of non-aromatic strained alkynes versus arynes. Experimental studies also demonstrated the rapid synthesis of polycyclic aromatic hydrocarbons, including tetracene and pentacene scaffolds, using this synthetic platform. The second part of the presentation will center on the development of an asymmetric Ni-catalyzed intramolecular cyclization of lactones to generate spirocyclic scaffolds using a combination of experiments and computations.

Juan David Ortiz is now facing capital murder and aggravated assault charges for the murders of four women and an attack on a fifth woman, who was able to escape. That woman was later identified as year-old Melissa Ramirez. She had been shot several times at point-blank range. Evidence at the scene collected included.

In September , a border town in Texas was rattled after four women who were sex workers were found dead. For days, Laredo authorities were hunting down every clue they could after they first discovered the bodies of Melissa Ramirez, 29, and Claudine Anne Luera, 42, who were shot and left on the outskirts of town.
