Oxy-Cope, and Siloxy-Cope rearrangement of cis-1-vinylcyclooct-3-en-1-ol

Creator:: Chin, Alice Wai-lee
Abstract:: Both oxy-Cope and siloxy-Cope rearrangements involve (1, 3) and (3, 3) sigrnatropic shifts. Both the concerted mechanism, and the stepwise mechanism via a diradical intermediate are possible. In a cyclic system such as cis-l-vinylcyclooct-3-en-l-ol, the thermal rearrangement takes place preferably through a diradical intermediate. At high temperature, the reaction also...

Siloxy-cope rearrangements of the trans-l-vinylcyclotridec-3-en-l-ol system

Creator:: Bolesta, Richard Edward
Abstract:: The thermolysis of trans-1 -trimethylsiloxy- 1-vinylcyclotridec- 3-ene (VI-OTMS) led to the formation of two major products: 4-vinylcyclotridecanone (VII) and cyclopentadec-5-en-l-one (VIII) after hydrolysis. Ketone VII is produced by a concerted [3, 3] sigmatropic shift, while ketone VIII is formed by a [1, 3] sigmatropic shift with a concerted or diradical...

Synthetic Studies towards Highly Oxygenated Furanyl Diterpenoids

Creator:: Goswami, Subir
Abstract:: The furanyl diterpenoid family of natural products has drawn the attention of both synthetic organic chemists and pharmacologists due to their complex structural architectures and diverse biological activity. Among them, wortmannin has been most extensively studied for biological activities. All these furanyl diterpenoids consist of a highly strained naptha[1,8-bc]furan core,...

Novel monolithic columns for microscale liquid chromatography and capillary electrochromatography

Creator:: Chirica, Gabriela S.
Abstract:: The challenges prompted by miniaturization of chromatographic systems have led scientists to explore new avenues in the synthesis of stationary phases. Packed capillary columns have found limited application in routine analysis due to a number of technical difficulties, most of which are attributable to the frits. New column designs insure...

Infrared investigation of some ferroelectric and related compounds : NH₄NCS, (NH₄)₂SO₄, RbHSO₄, and NH₄HSO₄

Creator:: Oden, L. L. (Laurance L.)
Abstract:: At liquid nitrogen temperature the spectra of sublimed films of NH₄NCS, both as phase I (the usual form stable at room temperature) and phase II (the low temperature form), exhibit detail usually reserved for gases at low pressures. In both phases the symmetry of ammonium ion has degenerated from tetrahedral...

High-resolution infrared studies of the ν10, ν11, ν14, and ν18 levels of [1.1.1]propellane

Creator:: Kirkpatrick, Robynne, Masiello, Tony, Martin, Matthew, Nibler, Joseph W., Maki, Arthur, Weber, Alfons, and Blake, Thomas A.
Abstract:: This paper is a continuation of earlier work in which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transitions involving three fundamental bands v₁₀ (E' - A'₁),...

Investigation of Chain Extension Approaches for the Stereoselective Reagent-Controlled Synthesis of alpha-Heteroatom Substituted Alkyl Boronic Esters

Creator:: Barsamian, Adam L.
Abstract:: Two distinct strategies were explored for the enantioselective synthesis of α-heteroatom substituted alkyl boronic esters by stereoselective reagent-controlled homologation using transient chiral carbenoid reagents CHYMX (Y = heteroatom, X = nucleofuge, M = electrofuge). In the first case, a stereospecific reagent-controlled homologation (sStReCH) approach to α-alkoxyalkylboronates using α-metalated S,O- and...
