Total synthesis of the proposed structure of yuremamine has been achieved for the first time based on the intermolecular [3+2]-cycloaddition reaction of the platinum-containing azomethine ylide. All the possible diastereomers of yuremamine were also synthesized via the common intermediate. Through these syntheses, it was confirmed that the proposed structure of yuremamine and the diastereomers differ from the natural product. The total synthesis of the proposed structure of yuremamine and its diastereomers has been achieved based on the [3+2]-cycloaddition reaction of the platinum-containing azomethine ylide. Its basic core skeleton, pyrrolo[1,2-a]indole skeleton, was efficiently constructed by this method at an early stage of the synthesis and a straightforward, short-step synthesis of the target products has been achieved.

(Chemical Equation Presented) The rational design, synthesis, and characterization of a series of novel perfluorinated dendrons 14a,b, 25a,b, 26a,b, and 18 are described. The dendrimers were designed to have a thiol at the focal point for attachment to a gold surface to enable the fabrication of self-assembled monolayers (SAMs). Perfluorinated tails were attached to the periphery to provide solubility in supercritical carbon dioxide, and to increase the hydrophobicity and the stability of self-assembled monolayers formed. Mitsunobu reactions were utilized to provide high-yielding steps allowing large-scale production of the novel dendrimers.
