Question
Chapter 27, Problem 27.39P
Interpretation Introduction
(a)
Interpretation: The products formed in the given cycloaddition reaction is to be predicted. The stereochemistry of given products are to be indicated.
Concept introduction: Cycloaddition reactions are pericyclic reactions that take place in two compounds containing pi bonds to form a cyclic compound. These reactions are concerted and stereospecific in nature. According to Woodward-Hoffmann rules, the polyene containing even number of bonds in photochemical conditions undergoes reaction in suprafacial fashion and polyene containing odd number of bonds undergo reaction in antrafacial fashion.
