• #### Synthetic approaches to molecular motors and conjugated oligomer libraries ﻿

(2005)
Chapter 1 describes the synthesis of four caltrop-shaped molecules that might be useful as surface-bound electrical field driven molecular motors. The caltrops have a pair of electron donor-accepter arms which form a strong ...

• #### Synthetic beauty: American women and cosmetic surgery ﻿

(1989)
This dissertation constitutes an anthropological inquiry into the current American boom in facial and bodily cosmetic surgery. The exploration of this phenomenon utilizes the messages of the print media, the literature of ...
• #### Synthetic Hydrogel Delivery of Growth Factors and Demineralized Bone Matrix for Bone Augmentation ﻿

(2014-04-24)
The overarching objective of this thesis was to investigate synthetic hydrogel delivery of growth factors and demineralized bone matrix (DBM) for bone augmentation. Our motivation rests on observed weaknesses of current ...
• #### Synthetic magnetogram calculations from magnetosphere-ionosphere coupling models ﻿

(2009)
Global MHD models, ring-current models, convection models, and a growing number of coupled models calculate the large-scale currents in the magnetosphere-ionosphere (MI) system. Traditionally, these models have been tested ...
• #### SYNTHETIC MU-IMIDAZOLATO AND MU-OXO BINUCLEAR COMPLEXES OF COPPER(II) AND IRON(III) PORPHYRINS AS MODEL COMPOUNDS FOR THE ACTIVE SITE OF RESTING CYTOCHROME C OXIDASE ﻿

(1983)
Several new and unique (mu)-imidazolato and (mu)-oxo binuclear complexes of iron and copper have been synthesized and characterized as models for the active site of cytochrome c oxidase. Characterization of these novel ...

• #### Synthetic routes to oxygenated aromatic and hydroaromatic phenanthrene derivatives ﻿

(1956)
Abstract Not Available.
• #### Synthetic Spin-Orbit and Light Field Coupling in Ultra-cold Quantum Gases ﻿

(2017-04-19)
Ultra-cold quantum gases subjected to light-induced synthetic gauge potentials have become an emergent field of theoretical and experimental studies. Because of the novel application of two-photon Raman transitions, ...
• #### SYNTHETIC STUDIES FOR THE TOTAL SYNTHESIS OF NAPHTHYRIDINOMYCIN ﻿

(1985)
Development of a synthetic route led to the synthesis of the tetracyclic compound 76a, a key intermediate for continued studies on the total synthesis of naphthyridinomycin.
• #### Synthetic studies of luzopeptins ﻿

(1997)
Luzopeptins are a series of cyclic depsipeptides which possesses potent antitumor and antiviral activities. There is no total synthesis of Luzopeptins has been achieved. In our own effort to synthesize the luzopeptins, we ...
• #### Synthetic studies on ecteinascidin 743 ﻿

(1995)
Synthetic studies on ecteinascidin 743 (b), an antitumor antibiotic, are described. The key reactions include: (1) an acylimmium ion-mediated stereoselective construction of the optically pure diazobicyclo (3.3.1) nonane ...
• #### Synthetic studies on naphthyridinomycin: A total synthesis of (+)-cyanocycline A ﻿

(1989)
A synthetic route via chiral precursor 74* had led to a total synthesis of (+)-cyanocycline A. This optically pure synthesis unequivocally determined the absolute stereochemistry of natural cyanocycline A as 2, in contrast ...
• #### Synthetic studies on the discorhabdins ﻿

(2000)
The discorhabdins are a family of chemically and biologically interesting natural products. Previous syntheses of these complex substances have all been very similar; this similarity is limiting to the flexibility of these ...
• #### SYNTHETIC STUDIES ON THE SAFRAMYCINS A, B AND S: A TOTAL SYNTHESIS OF SAFRAMYCIN B ﻿

(1985)
The Saframycins are naturally occurring antibiotics with an interesting bisquinone structure. The first and only synthesis of saframycin B is described herein. The interesting aspects of this synthesis are the convergent ...
• #### Synthetic studies toward an advanced intermediate of Fredericamycin A and the development and application of a novel palladium(0)-mediated spiroarylation ﻿

(1991)
An advanced intermediate 2 for the synthesis of antitumor antibiotic ($\pm$)-Fredericamycin $A$, 1, has been prepared. The synthetic route features a novel palladium(0)-mediated intramolecular spiroarylation of 3. This ...
• #### Synthetic studies toward the total synthesis of (+)-anthramycin total syntheses of (+)-neothramycins A and B ﻿

(1990)
Through the serendipitous discovery of a palladium catalyzed conversion of ethylthiol esters to their corresponding aldehydes, the pyrrolo (1,4) benzodiazepine systems found in (+)-anthramycin 1a* and (+)-neothramycins A ...
• #### Synthetic studies towards the luzopeptins: New amino acid synthons through the aza-Achmatowicz reaction ﻿

(1992)
A new method for the enantioselective synthesis of unusual amino acids has been developed. The chemoenzymatic aza-Achmatowicz rearrangement of appropriate furylglycine derivatives provided nitrogenous synthons that were ...
