Active site studies and design of ligands for affinity column separation of 2,5-dihydroxyacetanilide epoxidase (DHAE) I and II

Allen, Scott E. (2002-09-03)

A series of compounds, 7-8 and 20-25, were tested as competitive inhibitors of 2,5-dihydroxyacetanilide epoxidase I (DHAE I) and DHAE II. A Hammett plot was constructed for each enzyme to determine the effect of electr ...
Designing chiral rhenium (VII) trioxo complexes

Juniku, Rajan B. (2004-12-10)

The epoxide deoxygenation reaction is formally the reverse of the epoxidation reaction. Compared to epoxidation, which has reached its full maturity, epoxide deoxygenation has not been as intensively developed. Among ...
Direct atom transfer vs. ring expansion in reaction of rhenium oxo complexes with cyclooctene epoxides and episulfides

Khownium, Kriangsak (2003-08-11)
Evidence for a stepwise mechanism in the cycloreversion of rhenium diolates

Ness, Stephanie L. (1999-09-16)
Mechanistic studies of metal oxide mediated oxidation via kinetic isotope analysis of pentamethylcyclopentadienyl rhenium diolate cycloreversion

Phan, Thuy N. (1993-08-30)
New, complex group 13 borates : synthesis, structures, and properties

Chang, Ki-Seog (1998-02-05)
Rhenium-catalyzed oxygen-atom transfer reactions : mechanism and applications

Brown, Eric C. (2002-10-31)

In situ reduction of hydrido-tris-(3,5-dimethylpyrazolyl)borato(trioxo) rhenium(V) with triphenylphosphine or triethylphosphite leads to a reactive rhenium(V) species that catalytically deoxygenates epoxides at 75-105° ...
Studies on nitrogen containing secondary metabolites from terrestrial and marine origin

Barrios Sosa, Ana Carolina (2001-08-21)

PART I. A deuterium exchange analysis of 2,5-dihydroxyacetanilide (5) in the absence and presence of DHAE II was performed to test the nucleophilicity of the substrate in the absence and presence of catalyst. In addit ...
Studies toward the total synthesis of (+)-providencin

Jana, Somnath (2012-02-16)

Studies toward the total synthesis of (+)-providencin (1), a highly oxygenated cembranoid dipterpene with a unique bicyclo[12.2.0]hexadecane skeleton and pronounced biological activity, are described. These studies resul ...
Synthesis, characterization, and reactivity of rhenium dithiodiolate and monothiodiolate complexes

Chuawong, Pitak (2001-08-06)

The rhenium dithiodiolate, Hydrido-tris-(3 ,5-dimethyl- 1 -pyrazol yl) borato(ethane- 1 ,2-dithiodiolato)(oxo)rheni um(V), and Hydrido-tris-(3 ,5-dimethyl- 1 -pyrazolyl)borato(phenylethanedithiodiolato)(oxo)rhenium(V), ...
Synthetic studies on indolic enamide natural products: 1. Total syntheses of coscinamide A, concinamide B and igzamide: 2. Synthetic studies towards the synthesis of halocyamine B

Ma, Yuelong (2006-08-24)

The 3-substituded indolic enamide moiety has been found in many marine compounds over the past 20 years. These indolic enamides exhibit various biological properties such as cytotoxic, anthelmintic, antimicrobial and HW- ...
Tandem intramolecular photocycloaddition-retro-Mannich fragmentation as a route to indole and oxindole

Li, Yang (2012-02-22)

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 s ...
