Can you propose the pericyclic reaction mechanism and type of pericyclic reaction? 1. NH 2. H20
Pericyclic Reactions 1. Predict the products of the following reactions and propose a mechanism that explains it Me a heat OMCN heat 9. Ome =-COME HOY Y hest MeOC 2. Propose a synthesis of the following molecules using acetaldehyde as your only starting material 3. Propose a mechanism for the following transformations Meo,
4. (15 Points) Pericyclic Reactions: The transformation below can be described as a pericyclic reaction followed by a polar-acidic mechanism, where the acid is not shown because it is picked up from the environment. (a) Start by redrawing the starting material below, and show how the pericyclic reaction occurs with curved arrows. (b) Specify the type of pericyclic reaction it represents and the name reaction. (c) If you've done the pericyclic reaction correctly, your product will be an enol. From...
Propose a mechanism to account for the following reaction. 5. H20 H2SOs
propose a full, detailed mechanism for this reaction. thank you. NaoAc efor 0 NH me o 0 H O
Propose a reasonable mechanism for the following reaction (10 pts) NH OH OH -
No mechanism, please. Synthesis: a propose for synthesis. Thank you :) hesis NH₂ WH2
Please write 3 things: (1) the type of pericyclic reaction, (2) the formal number of electron pairs involved, and (3) whether the reaction is allowed thermally (write "A') or allowed photochemically (write "hv". If the reaction type is a sigmatropic shift, write it as "[m,al shift", where m and n are the appropriate numbers. Assume all sigmatropic shifts and cycloadditions are suprafacial.
