WebSep 24, 2024 · Ethyl acetoacetate is often confused with the acetoacetate ketone body, but only one is naturally made in your body. Ethyl acetoacetate, also known as ethyl 3-oxobutanoate, has been reported in coffee, passion fruit, and strawberries in minuscule amounts and is used as a flavoring agent in foods. WebOptically active ethyl 3-hydroxybutanoate is a very useful chiral building block for natural product synthesis. Some applications are shown in Table 1. Alkylation of doubly …
Web2:1 mixture of enantiomers obtained from the reduction of ethyl acetoacetate at room temperature provides a realistic illustration of the challenges of designing asymmetric reactions. Our Experiments For a series of undergraduate laboratory experiments, we investigated the reduction of a ketoester with and without the use of a chiral additive. WebThe remaining liquid contains the ethyl (S)-3-hydroxybutanoate that has been produced by chiral reduction of ethyl acetoacetate. A small amount of ethyl acetoacetate may remain unreduced in the sample. Reweigh the flask to determine the weight of the product. Calculate the percent yield of product. Obtain the IR spectrum of the product.
