January Update

January Update   I went back home to China during the winter break. It was nice to see my family since I haven’t been home for a year and a half. The break was necessary for I can reset myself from a busy semester where application, research and coursework were happening at the same time.

December Update

I have attempted my synthesis with a starting material that has a substituent group on the para position, which means the reaction is forced to take place on the ortho direction. I carefully carried out the procedure and used the 16-hour protonation step from my previous experiments. The resulting crude product appeared to be desirable.…

November Update

I have been occupied trying to separate para and ortho isomers from each other again for the new reaction. I have also noticed an important product peaking missing from the NMR spectrum. I reasoned that there was not enough time for the initial product to be protonated and went back to search for literature on…

October Update

October Update Up to this point, I have performed many synthesis of the precursor aldehyde and have successfully made it. However, the separation of the desired product from the product mixture has been difficult. The particular reaction I followed has a very poor regioselectivity. I went back and looked through literatures on this one specific…

September Update

September Update Following the synthetic success at the end of the summer, I continued to explore methods that can increase the overall yield of my desired precursor product. I researched different experimental methods that can lead to the same product with better yield. The synthesis was plain and simple; however, the purification was not. I…
