ALKYLATION AND OXIDATIONS OF SYMMETRICAL DIMETHYLENEBIPHENYL AND RELATED DIANIONS (CYCLOPHANE, BIPHENYLOPHANE, NMR, CONFORMATION).
Bis-benzyl dianions were prepared from the three symmetrical dimethylbiphenyls in yields of 79-86%, and shown to react with a variety of electrophiles on the benzylic carbons. Electrophiles included dimethyl and diethyl sulfate, isopropyl bromide, t-butyl iodide, allyl chloride, trimethylsilyl …

Synthesis of D-alanyl-D-alanine dipeptide isosteres and cephalosporin prodrugs
… linkages in the growing peptidoglycan cell wall. Synthesis of dipeptide isosteres which may be incorporated into the growing cell wall is described. Previously published syntheses were employed as well as a Wittig reaction using a chiral Wittig reagent, a reaction not used in the synthesis of …

In pursuit of conjugation in one-dimension: Synthetic studies of oligomeric and polymeric organic materials
… in and related diphenycyclooctadiynes, these compounds do not readily undergo ring-opening alkyne metathesis polymerization (ROAMP), even with the most active alkyne metathesis catalysts available. The ring-opening of 1 proceeds via a tungstenatetrahedrane intermediate. Because of its sluggish …

Two enantiodivergent syntheses of balanol and the chemoenzymatic synthesis of oseltamivir
… the Burgess reagent and its application to the synthesis of enantiomerically pure ~-amino alcohols. This methodology has been exploited in the formal enantiodivergent synthesis of the (+)- and (-)-isomers of balanol. Also described is a second generation approach to both balanol enantiomers; …

Development of new synthetic methodologies
… treatment of aldehydes with acetylenic carbonyl compounds in the presence of TiCI4 as the Lewis acid promoter. The reaction proceeds through the formation of halo aldol adducts. These adducts have been isolated in good yields, which extends the application of classical aldol reaction. A similar …

A hydrogen bonding ortho-directing effect for the iridium catalyzed borylation of NH(t-BOC) aromatics
The C-H borylation of aromatic substrates has evolved from a stoichiometric curiosity to a valuable methodology for the synthetic chemist. Understandings of regioselective activation and high functional group tolerance have been considerably praised. Most aromatic substituents, such as alkyl, …

Design and synthesis of dihydronaphthalene vascular disrupting agents and indolequinone-based bioreductives.
… In this study, efforts were directed towards the synthesis of two combretastatin analogs bearing key features of CA4 on a dihydronaphthalene framework: Oxi 6196 and a beta-dihydronaphthalene analog. In addition to VDAs, another class of exciting anticancer drugs is bioreductive agents that are …

Development of a microwave-assisted epoxide aminolysis and investigation of the aza-cope rearrangement--mannich cyclization for alkaloid synthesis
<p>β-Amino alcohols are important organic compounds with numerous applications. Commonly β-amino alcohols are prepared by ring opening of epoxides using an amine nucleophile and a catalyst or promoter. Ring opening can take place by the SN1 pathway or the SN2 pathway, but no single catalyst or …
