Abstract – The synthesis of 4-hydroxy-4‚4-diphenylbutn-2-one was a three week multi-step project. The steps involved protecting the ketone of ethyl acetoacetate with a ketal group‚ followed by preparation and reaction with Grignard‚ then purification by extraction and recrystallization. The yield was 78.5%‚ but there are impurities present suggested by 1H-NMR‚ IR‚ and TLC. However‚ the results do indicate the desired hydroxyketone was formed. Introduction: The purpose of this multi-step lab

Abstract: This experiment synthesized H-Gly-Phe-OH dipeptide using “Fmoc chemistry”. The first part of experiment was the synthesis of L-phenylalanine methyl ester hydrochloride. The methyl ester can be synthesised by reaction of thionyl chloride‚ SOCl2 and dry methanol with L-phenylalanine under reflux condition. The peptide bond was formed later in the experiment‚ where HBTU‚ DiPEA and a solution of Fmoc-Gly-OH in DMF were added to a solution of L-phenylalanine methyl ester hydrochloride in DMF
