Inter- and intramolecular (4+2) cycloaddition reactions and tandem inter- and intramolecular (4+2)/intramolecular (3+2)cycloaddition reactions of nitroalkenes
Both inter- and intramolecular cycloadditions of nitroalkenes with Lewis acid catalysis were investigated. The intramolecular cycloadditions of nitroalkenes were found to be completely stereoselective for trisubstituted nitroalkenes. Intermolecular cycloadditions of aromatic nitroalkenes were found …

Investigations of transition state geometry in the intramolecular aldol reaction and the intramolecular reaction of allylsilanes with aldehydes
… model systems designed to study base-catalyzed intramolecular aldol reactions are reported, along with the effects that various metal counterions, solvents, and additives have on the stereochemical course of cyclization in these models. These models are the first to provide data concerning the …

Toward the Understanding of Intramolecular Energy Transfer
Intramolecular electronic energy transfer is intimately related to vibrational energy transfer in many ways, both in the systems studied and in the computational methods employed. Due to the rapid rise of interest in molecular computing, understanding the more complicated electron transfer problems …

Intramolecular (4+2); and tandem intermolecular (4+2);/intramolecular (3+2); cycloaddition of nitroalkenes with achiral and chiral dienophiles
… activated and unactivated olefins were prepared. Intramolecular cycloadditions with both acyclic and cyclic dienophiles in the presence of SnCl$\sb4$ were investigated. Nitroalkenes tethered with three methylene units to a Z-dienophile afforded trans fused nitronates. The cycloaddition towards …

Intramolecular Reactions of Trivalent Phosphorus and Carbonyl Functions
Phosphonous diesters derived from the reaction of phenylphosphonous dichloride with 2-ketophenols readily undergo head-to-tail oxidative cyclization to yield stable tricyclic phosphoranes in cases where the carbonyl function is an aldehyde, trifluoroacetophenone, or diaryl ketone. A methyl imine …
