4. For the following reactions, develop a transition-state structure using molecular models which would account for the observed stereoselectivity. Also, describe the type of pericyclic reactions using the proper terminology. (each Br heat A & Br b) F 0°C F heat heat d) product? =& & MeO₂C OCH3 H HO 1. CO₂Me مر CO₂Me LOCH3 heat heat MeO₂C HO

Consider this scheme. Why does a ring form with a single ethylene glycol on A rather than two molecules of ethylene glycol to form acyclic acetals? Intramolecular reactions are A unfavorable when compared to intermolecular reactions Acyclic molecules are unfavorable compared to rings В in all cases The change in entropy is favorable for ring formation and strain is low in a five- membered ring Sterics prevents acyclic molecules from forming in this D case H HCI + HOCH2CH2OH H + H2O
For the cycloaddition reaction shown below A B NC CN a) Give the curved arrow-pushing and draw the allowed product for the reaction, be sure to include stereochemistry and indicate any racemic mixtures A heat b) on TOP of reactant A draw a pictorial representation of the HOMO (draw it on the structure like the one shown below rather than the one in the equation so that the curved arrow-pushing isn't obscured) B c) on TOP of reactant B draw a pictorial representation of the LUMO (draw it on the structure below rather than the one in the equation so that the curved arrow-pushing isn't obscured) NC CN d) Is the allowed reaction suprafacial or antarafacial for reactant A? e) Is the allowed reaction suprafacial or antarafacial for reactant B?
