Abstract:: Complex organic transformations, such as the addition of pyrrole to ketene using planar chiral organocatalyst (*PPY), the four-component anhydride- Manniach reactions, and the site-selective desymmetrization of meso-1,2-diol, are remarkable synthetic reactions that provide high yield and high selectivity. However, the exact mechanism and origins of stereocontrol for theses synthetic organic...

Abstract:: This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...

Abstract:: Thermal decomposition of several di-p-toluenesulfonylhydrazones was studied. It was found that the carbene decomposition of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone gave two products resulting from rearrangement. One was identified as 2,5-dimethyl-1,3,4-hexatriene. A tentative structure for the second was proposed. During the course of the study, a more convenient procedure for thermal decompositions was...

Abstract:: An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride with aluminum chloride was shown to give one bicyclic chlorine containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...

Abstract:: Irradiation of a tryptamine linked through its side-chain nitrogen to an alkylidene malonate residue results in an intramolecular [2 + 2] cycloaddition to the indole 2,3-double bond. The resultant cyclobutane undergoes spontaneous retro-Mannich fission to produce a spiro[indoline-3,3-pyrrolenine] with relative configuration defined by the orientation of substituents in the transient...
