During this laboratory session we will use the Claisen rearrangement to transform phenyl allyl ether (1) into 2- allyl phenol (2). The phenol results from the tautomerization of the initial product of the Claisen rearrangement to restore aromaticity as shown below. You have yet to learn that keto-enol tautomerization usually favors the ketone, but in this case the restoration of aromaticity provides a driving force for the formation of the enol).

Hints for identifying compounds in multiple-choice problems (problems 1:5); 1. Closely compare the given compounds. Determine which piece of information (molecular weight from MS, number of peaks in the NMR, presence of a special functional group in the IR, etc) would be the easiest for distinguishing between the given compounds. You might not need to use all types of given spectra to find your correct compound! 2. Based on your answer from step 1, consult the appropriate spectrum first. For...

1151 VCL 11-8: Claisen Condensation -1 For this assignment, the target compound that you should synthesize is methyl acetoacetate. This is another carbonyl addition variation. Examine the product and determine which ester is the nucleophile and which is the electrophile. Keep in mind the mechanism and that you need to acidify the intermediate in order to isolate a neutral product. Synthesis Procedures 1. Start Virtual ChemLab and select Claisen Condensation-I from the list of assignments in the electronic workbook. After...

11-4: Aldol - 1 For this assignment, the target compound that you should synthesize is 2-ethyl-3-hydroxy-hexanal. This is a symmetric aldol reaction. Examine the product and determine which bond may be formed to link the two aldehydes. Keep in mind the mechanism and identify the nucleophile and the electrophile. Synthesis Procedures 1. Start Virtual ChemLab and select Aldol – 1 from the list of assignments on the whiteboard. After entering the synthesis laboratory, use the...
