The number of acetate and propanoate units are to be determined in the given structure of (+)-Discodermolide . Concept Introduction: An acetate unit contributes two carbon atoms in a synthesis while a propanoate unit contributes three carbon atoms. In (+)-Discodermolide (C 33 H 55 NO 8 ) , there are in all 33 carbon atoms out of which one is a part of the amide group and does not come from either acetate or propanoate. The methyl carbon atom in propanoate is the beta carbon atom and remains unreacted in the synthesis. The number of methyl groups indicate the number of propanoate units in the synthesis.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

Predicting As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: H₂N O H 1. ? 2. H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.
