Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

Creator:: Melbardis, John
Abstract:: In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...

Formation of alkyl-and dialkylcarbenes. The 3-cyclohexenyl carbinyl carbene system

Creator:: Crouse, Dale McClish
Abstract:: The 3-cyclohexenyl carbinyl carbene species was formed by the thermal decomposition of the p-toluenesulfonylhydrazone sodium salt and by oxidation of the hydrazone. Several oxidizing agents were studied. The products were investigated under aprotic and protic conditions and at various temperatures. The diazocompound was formed as an intermediate and found to...

Photochemistry of 6-alkenyl-2-cyclohexenones : synthetic studies towards precursors of ryanodol

Creator:: Wang, Bingbing
Abstract:: Regiochemistry of intramolecular [2+2] photocycloadditions of oxygenated 6-alkenyl-3-alkoxy-2-cyclohexenones is studied. Application of this methodology to construct a key intermediate [3.3.2] bicyclic skeleton of ryanodol is described as well. Irradiation of (3-butenyl)compounds 3, 11, 14 and of (4-pentenyl)compound 6 afforded exclusively the linear photoadducts 4, 12, 15 and 7 respectively. Irradiation...

The effect of hydrogen ion concentration upon the absorption of dyes by cellulose and fillers

Creator:: Kuykendall, Delman Vernon
Abstract:: The dyeing of paper is one of the most important processes in the manufacture of that material. Fully 95 percent of the paper that is produced is colored to a greater or lesser extent, and in many eases the reproduction of a shade is essential. That pH is an important...

A study of the chemical composition of Ca-Al-rich inclusions from the Allende Meteorite

Creator:: Conard, Roberta
Abstract:: Nine Ca-Al-rich inclusions and one olivine inclusion from Allende meteorite were studied for Ti, Al, Fe, Mg, Ca, Na, Cl, K, Sc, V, Cr, Mn, Co, Ni, Zn,Hf, W, Ir, Au, Ta, and Re -via INAA (instrumental neutron activation analysis) and REE, Ba, Sr via RNAA (radiochemical NAA). The inclusions...

The chemical composition of 61 individual Allende chondrules

Creator:: Warren, Richard Gregory
Abstract:: The abundances of 12 elements, Fe, A1, Na, Ni, Cr, Mn, Co, Ca, Sc, Ir, Sm and Eu have been determined by INAA in 61 individual chondrules (0.1-100 mg) separated from five Allende (C3) meteoritic fragments ( 25g). Ti and V have been determined in 18 of these chondrules, and...

Low-Dose X-Ray Radiation Effects On the Proteomic Profiles of Hippocampus, Cortex, and Cerebellum of Contextual Fear Conditioning and Novel Object Recognition Trained Mice

Creator:: Koluda, Rony
Abstract:: Radiation exposure to the brain can occur from a variety of events, including space missions, nuclear accidents, and clinical treatments. The effects of high dose radiation are well studied, but those of lower dosage are more elusive. Decline of memory and cognition is observed in patients exposed to low dose...
