- Choose among the synthetic steps provided in order to propose a reasonable stepwise preparation of the following compound A starting from benzene.arrow_forwardplease help with this question. thank you. The following sequence, beginning with a cyclic hemiacetal (compound A), was part of a recently reported enantiospecific synthesis of a powerful sex pheromone (currently used in pest management) of the mealybug Pseudococcus viburni: Draw the structures of compound B and C. Provide a plausible mechanism to explain the transformation from compound C into compound D. Identify the reagents you would need to convert compound D into compound F (in just two steps). Also identify the structure of compound E.arrow_forwardOutline a synthesis for the following transformation and provide a justification for your chosen strategy. (More than one steps may be required)arrow_forward
- Provide reagents and conditions for the following synthetic tranformation. (Please don't provide handwritten solution)arrow_forwardDraw a complete arrow pushing mechanism for the specific Friedel Crafts acylation which involves the acylation of 1,3-benzodioxole using propionyl chloride as the acylating agent in the presence of zinc oxide nanoparticles as a catalyst. This reaction results in the formation of a propionylated product. The reaction is facilitated by the Lewis acid catalysis provided by zinc oxide nanoparticles.arrow_forwardThe ketone shown was prepared in a three-step sequence from ethyl trifluoroacetate. The first step in the sequence involved treating ethyl trifluoroacetate with ammonia to give compound A. Compound A was in turn converted to the desired ketone by way of compound B. Fill in the missing reagents in the sequence shown, and give the structures of compounds A and B.arrow_forward
- Compound A is first reacted with methylamine in the presence of acid and then treated with NaBH3CN. Using the spectroscopic data given, what is the structure of the product after step 1?arrow_forwardExplain how benzaldehyde and dimedone reacts with each other, and then with the aminotriazole to form compound 1a in the presence of an acid catalyst. Provide a detailed reaction mechanism and explanation.arrow_forwardIdentify A, B, and C, intermediates in the synthesis of the five-membered ring called an α-methylene-γ-butyrolactone. This heterocyclic ring system is present in some antitumor agents.arrow_forward
- Considering the reaction below, identify compounds A, B, and C. Provide the IUPAC names of each of them.arrow_forwardGive the major product of the following reaction for letter b) and explain the mechanism/processarrow_forwardSuggest reasonable explanations for each of the following: A. The rate of saponification of ethyl p-nitrobenzoate is 200 times faster than that of ethyl p-methoxybenzoate. B. The rate of saponification of methyl acetate, CH3CCO2CH3 is 50 times greater than that for isopropylacetate.arrow_forward
