Abstract The Diels-Alder cycloaddition reaction of -diethylphosphonyl cyclohex-2-en-1-ones 34 and 37 and subsequent transformations of resulting cycloadducts are described in this thesis. Part one dscribes the Diels-Alder cycloaddition reaction of enones 34 and 37, which were synthesized using known procedures. Enones 34 and 37 were found to be effective dienophiles, giving the expected cycloadducts in good to excellent yields and within a reasonable period of time. The reaction was found to follow the ortho- and para- rules and gave the endo-to-ketone product. Of all the Lewis acids investigated, tin chloride was deemed to be the most effective Lewis acid. Part two describes the use of lithium naphthalenide as an efficacious reducing agent in the removal of the angular alkyl phosphonyl group in the above-formed cycloadducts. The resulting enolate was then trapped with a variety of alkylating agents, giving in all cases, a cis-ring junction. Part three describes an interesting use of the phosphonate containing cycloadducts mentioned above in a Wittig type reaction. The above- formed cycloadducts were first treated with a variety of Grignard reagents. The resulting 1,2-adducts 68 and 69 were then treated with potassium hydride in the presence of 18-crown-6 to give various rearrangement products 70 and 71.

Part I. An Indium Promoted Asymmetric Allylation in Aqueous Cyclodextrin Solution In this thesis we discussed about the allylation reaction promoted by indium using cyclodextrins as an auxiliary in aqueous solution. The effects of indium equivalent, cyclodextrin concentrations and solution temperature were studied, and the allyl aryl alcohols were obtained in 60~90% yield and a maximum of 24% e.e. was achieved. The failure to achieve a high e.e. value when using cyclodextrins as an auxiliary is due to the shallow binding of cyclodextrin complexes and a dynamic equilibrium exists in the guest and host (CD), therefore only a small difference in the stereo-selectivity was achieved. Part II. Photochemistry of Cyclohexenones Containing Cyclopropyl Coumpounds In the second part of this work, we have studied the photochemistry of cyclohexenone compounds containing cyclopropyl group, i.e. 74 and 75. The expected ring-opening reactions of these cyclopropyl containing compounds were not observed, instead, compound 74 underwent a photo-[2+2]cycloaddition to yield 76. The configuration of compound 76 was assigned to be an anti-hh dimmer based on its 1H- and 13C NMR spectra and its similarity in chemical shifts with known structures. The anti-hh 76 was latter confirmed by an X-ray crystallographic analysis. Compound 75 underwent a Photo-Fries rearrangement and also gave compound 77 as the sole product. The structure of compound 77 was also confirmed by NMR and X-ray studies. Presently the reaction mechanism is not known.
