Alum Success

“The material covered in LSSU's engineering program provided me a solid foundation for graduate studies. The systematic approach and communication skills needed to tackle engineering projects were taught and then practiced over and over again. In particular I appreciate the many hours spent by the faculty to develop oral presentation skills in each student. As a graduate student now, these skills have proven to be highly beneficial and, to my surprise, obviously not taught to the same extent at many other universities.”

Synthesis of Multicyclic Products ...

Josh Brown

“Synthesis of Multicyclic Products from Annulation Reaction of an Imadazoline and β-Hydroxy Carboxylic Acids”: Imidazolines are nitrogen containing hetercycles that can be found in natural products. They have unique properties particularly their ability to react with electrophiles and nucleophiles. If reacted with a molecule that contains both, imidazolines can undergo annulations to produce many interesting products. This study attempted to prepare a multicyclic product from the reaction of 1-benzyl-2-phenyl-2-imidazoline with salicyloyl chloride or salicylic acid under three different conditions to determine which was optimal. The first reaction is a two step process that uses salicyloyl chloride produced from salicylic acid. The salicyloyl chloride is then used in an annulations reaction with the imidazoline. Production of salicyloyl chloride by known methods failed. Conditions two and three attempted a similar annulations using the coupleing reagents BOP-Cl and EDC with salicylic acid and the imidazoline. These reagents work to bond the carboxylic acid to the imidazoline N and make the reaction one step. The EDC reaction failed to produce the right product, the BOP-Cl reaction appeared successful based on GCMS. However, during the purification the product was not able to be isolated.
