Anastasia PassalarisLab Report #1The diels-alder reaction forms an intermediate before compound Y is made. Thisintermediate’s stereochemistry and structure can be determined by the diels alder reaction. Afilled pi molecular orbital from the diene (hexadien-1-ol) contributes electrons to the empty pimolecular orbital of the dienophile (maleic anhydride). This flow of electrons creates a newsigma bond, connecting the two reagents to form a ring. Based on the positions of the twofunctional groups on the diene, they have to be on the same plane, along with the the fivemembered ring that is attached to the six member ring, according to the endo rule. This structurehelps to determine the stereochemistry of compound Y.The IR spectra had a fairly broad peak at 3280 cm^-1. This is most likely due to O-Hstretching of an alcohol. The peak is weak, which indicates that there are probably intramolecularforces affecting the OH group. This makes sense, because the OH group in compound Y is closeto the ester that is attached to the ring. The peak at 3001 cm^-1 is indicative of C-H stretching inan alkene (sp^2) and the peak at 2897 cm^-1 is C-H stretching of an alkane (sp^3). The peak at
