NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Over the past several decades, chemists have developed a number of synthetic methodologies for the synthesis of steroid hormones. One of these, developed by Lutz Tietze at the Institut für Organische Chemie der Georg-August-Universität, Göttingen, Germany, used a double Heck reaction to create ring B of the steroid nucleus. As shown in the following retrosynthetic analysis, a key intermediate in his synthesis is compound (1). Two Heck reaction disconnects of this intermediate give compounds (2) and (3). Compound (2) contains the aromatic ring that becomes ring A of estrone. Compound (3) contains the fused five- and six-membered rings that become rings C and D of estrone. Q.Propose structural formulas for compounds (2) and (3).

1. how many stereoisomers are possible for 9,10- dibromo hexadecanoic acid? 2. Addition of bromine to palmitoleic acid primarily yields a set of enantiomers, (±) -three-9,10-dibromo hexadecanoic acid. The addition of bromine is an anti-addition to the double bond (ie, it appears to occur through the intermediary of the bromonium ion). Taking into account the stereochemistry of the cis double bond of palmitoleic acid and the stereochemistry of adding bromine, Write a three-dimensional structure for (±) -three-9,10-dibromo hexadecanoic acid!
