Studies toward the total synthesis of alkaloids : nagelamide A and D, agelastatin D, dragmacidin A-C, salacin and almazoles

Creator:: Tonsiengsom, Sorasaree
Abstract:: Studies toward the total syntheses of highly potent cytotoxic alkaloids including the bromopyrrole alkaloids and indole alkaloids were conducted and are described. Studies carried out in the course of this dissertation consist of five total syntheses of natural products that include bromopyrrole alkaloids nagelamide A, D and agelastatin D as...

I. Isolation of certain toxic components of kraft mill waste and attempts to determine their structure. ; II. Studies of the mechanism of the cope rearrangement of 1,2-divinyl-1, 2-cyclohexanediol

Creator:: Banks, Richard Charles
Abstract:: PART I. A chemical examination of the materials toxic to fish in kraft pulp mill wastes has been made as part of a water pollution study. Thirty gallons of "foul condensate" from a typical kraft mill gave 14 g of organic material when extracted with methylene chloride, and an additional...

Development of Carbenoid Eliminative Cross-coupling for the Stereocontrolled Synthesis of Trisubstituted Alkenyl Moieties Within Styrenes and 1,3-Dienes

Creator:: Tanpure, Subhash D.
Abstract:: Traditional approaches for the direct preparation of alkenes are unable to fully control either the stereochemical configuration of the carbon-carbon double bond or else the regiochemistry of the substituents surrounding it. The recently introduced concept of carbenoid eliminative cross-coupling (CEXC) offers a remedy to these deficiencies by providing for a...

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...

Ring expansion reactions of alkoxides and their application toward synthesis of large ring hormone models

Creator:: Seitz, Earl Philip
Abstract:: The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...
