Determine the mechanism for cleavage reaction of the p-Dimethoxytrityl (DMT) ether. Concept introduction: The cleavage reaction of p-Dimethoxytrityl (DMT) takes place by the S N 1 mechanism. The S N 1 reaction is nucleophilic substitution reaction in which nucleophile is replaced by a leaving group. S N 1 indicates unimolecular, substitution and nucleophilic reaction. S N 1 reaction takes place in following two steps: Leaving group leaves and leaves behind carbocation intermediate. Nucleophilic attack on the carbocation to form final product. The stability of carbocation i.e. 3°>2°>1°, determines the rate of the reaction. Given information: The information given in the question is that the DMT ether is easily cleaved by the treatment with mild acid.

Question

A synthetic organic molecule, G, which contains both aldehyde and ether functional groups, is subjected to a series of reactions in a multi-step synthesis pathway. In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group. Don't use chat gpt.

The ether, CH3OCH2CH3, can be prepared by two different nucleophilic substitution reactions, one using CH3O- as nucleophile and the other using CH3CH2O- as nucleophile. Draw both routes.

Sharpless epoxidation of allylic alcohol X forms compound Y. Treatment of Y with NaOH and C6H5SH in an alcohol–water mixture forms Z. Identify the structure of Y and draw a mechanism for the conversion of Y to Z. Account for the stereochemistry of the stereogenic centers in Z. Z has been used as an intermediate in the synthesis of chiral carbohydrates.
