synthesis: how to get this molecule?
thesis+B 20 AM 1. Outline a synthetic strategy that could be used to efficiently synthesize the following, products. You may use oxacyclopropane, benzene, cyclohexane and any, alkene, alkyne, alcohol, or alkyl halide that is four carbon atoms or less. You may also use any organic solvents necessary and standard reagents as needed.

Show, by writing a series of synthetic steps how you could prepare the following target compound for the designated two starting materials (a cyclic diene and acetylene) and any other necessary organic or inorganic reagents. You must also show all the intermediate structure(s) for your synthesis indicated by the "?" marks. More than one step will be needed. H CH,CH, CH CHH + H-C=C-H ? ?

This experiment involves the synthesis of a target molecule using Grignard reagents. You must do the following: 1. Perform a retrosynthetic analysis on the target molecule. The organic starting material (what you have to work backwards toward) is provided. Draw a retrosythetic scheme; use the rightwards double arrow to show functional group transformations and disconnections. Provide synthons and synthetic equivalents for every disconnection made. 2. Propose the...

Part IV - Multistep Synthesis [14 marks] A. Propose a synthesis of compound A starting from dimethyl malonate. When choosing your synthetic steps, you can use any hydrocarbon with three or fewer carbon atoms, any solvents or inorganic reagents, and any organic reagents that do not contribute carbon atoms to the carbon skeleton in the product. Clearly show the required reagents and the product of each step. You do not need to show mechanistic (curved) arrows. [6 marks] Dimethyl malonate...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

Part B What are the differences between the adrenal hormone cortisone and the synthetic corticoid prednisone? Check all that apply. They have different nuclei. Cortisone has three ketone groups, but prednisone has two. Cortisone has two methyl groups, but prednisone has three. Cortisone has two hydroxyl groups, but prednisone has only one hydroxyl group. Prednisone has a second double bond on the first ring. Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining Review | Constants 1...
