Interpretation: The stereochemical pathway for the given cycloaddition
Concept introduction: The Diels-Alder reactions are the chemical reactions in which diene and dienophile participate to form Diels-Alder adduct. The diene compounds should be conjugated. Conjugated compounds contain at least one single bond in between two double bonds.

- A novel heterocyclic compound, M, contains nitrogen and sulfur atoms and exhibits interesting photochemical properties. When exposed to ultraviolet (UV) light at a specific wavelength, M undergoes a photoreaction resulting in two products: N and O. Product N is formed through a [2+2] cycloaddition involving the nitrogen atom in M, while product O results from a homolytic cleavage of a sulfur-sulfur bond in M. Given these reaction pathways, what is the most probable structure of M, and what are the likely structures of N and O? A. M is a thiazole derivative; N is a dimerized product through the nitrogen atoms, and O is a compound with two sulfur-centered radicals. B. M is a diazine derivative; N is a tetra-atomic cyclic compound, and O is a compound with two separate thiol groups. C. M is a thiadiazole derivative; N is a four-membered ring involving the nitrogen atom, and O results in two sulfur-centered radicals. D. M is a dithiolane derivative; N is a dimer involving the nitrogen…arrow_forwardPredict the stereochemistry of the following Pericyclic reactions a) a thermal [2 + 6] cycloaddition b) photochemical [3 ,6] sigmatropic rearrangementarrow_forwardIdentify two alkenes that react with HBr to form 1-bromo-1-methylcyclohexane without undergoing a carbocation rearrangement.arrow_forward
