Please draw efficient syntheses (the fewest number of steps that avoid competing reactions and gives the highest synthetic yields). Identify all reagents by structure or proper abbreviation. Draw the structure of each product that is made for each of the individual reaction steps in your synthesis (do not just list 5 reagents above one arrow drawn in between the starting material and the product...). Please read attached image for further instruction.

Midterm 1 Study Guide - Examples of syntheses using alkyne and alcohol chemistry Please draw efficient syntheses (the fewest number of steps that avoid competing reactions and gives the highest synthetic yields). Identify all reagents by structure or proper abbreviation. Draw the structure of each product that is made for each of the individual reaction steps in your synthesis (do not just list 5 reagents above one arrow drawn in between the starting material and the product..... You may use any reagents we discussed in class, including organometallic reagents. Strategy: Use a retrosynthesis approach to identify the parts of the product that you can synthesize ultimately from the starting material shown. Then, use those parts to 'reassemble', that is, to synthesize the product in the forward direction. Please make sure you draw the forward synthetic direction for your syntheses. Do not show any mechanisms for these synthesis reactions, just indicate the reagents that you use for each step. (1) Examine the differences between starting material and product. 2) Count carbons to determine if you need to add carbons to the starting material for lose carbons) to make the product. 3) Disconnect the bond that makes the most sense such that the two parts that you have you know how to react them back together and you know how to make those parts.... 4) You might end up showing the synthesis of individual structures that are components of the product by using this retrosynthesis approach that you then show their reaction together to form the product.] 1. yu 2. 3.
