3. (2 points) Provide a mechanism, using curved arrow notation, for the formation of glycine and acetaldehyde from threonine. This process occurs by a PLP-dependent enzyme, you may begin your mechanism with the "PLP-primed" enzyme. Be sure to pay careful attention to stereochemistry throughout your mechanism. You may abbreviate any iminium formation, iminium hydrolysis, and transaldimination steps in your mechanism by the conventions shown in lecture.

h Provide the produet and a detailed step-by-step mechanism for the reaction below 20 points) Na OCH, in CH OH 5. (a) Enamines react with acid chlorides in the same way as do other nucleophiles, and the result (after workup with water) is a dicarbonyl compound; this is sometimes called the Stork enamine acylation, after Prof. Gilbert Stork who developed this chemistry. No new ring is formed during this reaction. Please provide the product and a...
