Predict the product of the following process: Predict the major product(s) for each of the following thermal electrocyclic reactions. 17.21a Modify the given copy of the starting material to draw the major product(s). Use the single bond tool to interconvert double and single bonds, and use wedges and dashes to indicate the stereochemistry of any newly formed chiral centers. If more than one stereoisomer is produced, draw both products. Note: you can save time drawing by selecting a structure and using the copy/paste function. Draw the product for each of the following electrocyclic reactions. Using wedges and dashes, indicate the stereochemistry. If more than one stereoisomer is produced, draw both products. Heat ?
