Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...

Can you help me identify reagent (i), Compound 8 and
Compound 12 in the reaction scheme?
You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
The lab data for Compound 8 and 12 is as
follows:
You can use any...

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...

**(left structure)****(right

The two structures for the assignment are above and
the task is:
1. Perform a retrosynthetic analysis on the two target
molecules assigned to you. In each case the organic
starting material (what you have to work backwards toward) depends
upon the target. For the structure given above (structure on left),
the starting material is either malonic ester or acetoacetic ester
and any halide. For the structure given above (structure on right),
the starting material is any...
