Book excerpt: Although the chemistry of benzenoid and nonbenzenoid quinones have been the subject of extensive theoretical and experimental studies, the extent of our present understanding regarding the geometries and stabilities of quinones of pentalene is meager. After studying the existence of cyclopentadienone and its reactivity as a diene and dienophile in the literature, the study of some related species, particularly the ones with fully unsaturated pentalenic structures were started. In this thesis, the elusive compound bicyclo[3.3.0]octa-3,5,8-triene-2,7-dione was tried to synthesize by using the synthetic strategy which was developed by us. We used cycloheptatriene as the starting material. The bicyclic endoperoxiedes mixture obtained by the photooxygenation of cycloheptatriene was v treated with triethylamine to give tropone in high yield. Selective reduction of tropone afforded cyclohepta-3,5-dione which was converted by the way of photochemistry to the bicyclo[3.2.0]hept-6-en-3-one. After protection of the carbonyl group, dibromocarbene was added to the double bond to give desired bicyclic compound with pentalene skeleton. Substitution of the allylic bromide with hydroxyl group followed by PCC oxidation resulted in the formation of a diketone. All efforts to convert this diketone into fully conjugated system failed.

This book was released on 2016 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Chapter 1, rearrangements of 4-substituted bicyclo[2.2.2]oct-2-enyl-5-selenophenyl esters are explored. Reduction of the esters under radical-generating conditions initially generates a bicyclo[2.2.2]oct-5-en-2-yl radical which can rearrange to a bicyclo[3.2.1]oct-6-en-2-yl radical via a cyclopropylcarbinyl radical. Although the bicyclo[3.2.1]octene system exhibits greater strain than does the bicyclo[2.2.2]octene system, radical-stabilizing substituents can reverse this preference. The product ratios are influenced by the interplay of ring strain and radical stability. In addition, the rearranged products favored the equatorial over the axial isomers, which can be explained by torsional steering. In Chapter 2, different approaches to the synthesis of the optically active bicyclo[2.2.2]octane-2,5-diones are presented. A stereoselective Diels-Alder cycloaddition was explored to construct the bicyclo[2.2.2]octane skeleton in an efficient manner. This approach was hindered by unexpected polymerization and lack of stereoselectivity. A different method of synthesizing the optically active bicyclo[2.2.2]octane-2,5-dione featuring a diastereoselective 1,4-addition is also presented. In Chapter 3, progress toward the total synthesis of parthenolide is described. The synthetic route relies on ring-closing metathesis to close the 10-membered carbocycle of the natural product. The efforts leading up to and including the key ring-closing step are described. Specific attention is given to different methods for overcoming the difficulties associated with medium-sized ring formation.
