Green Chemistry Using Bismuth(Iii) Salts: Synthesis Of Cyclic Acetals And Allylation Of Tetrahydropyranyl Ethers And Aldehydes, Scott W. Krabbe
Green Chemistry Using Bismuth(Iii) Salts: Synthesis Of Cyclic Acetals And Allylation Of Tetrahydropyranyl Ethers And Aldehydes, Scott W. Krabbe
Honors Projects
Research in our group focuses on environmentally friendly organic synthesis using bismuth compounds. With increasing environmental concerns, the need for environmentally friendly organic synthesis following Green Chemistry principles has assumed increased importance. The Pollution Prevention Act, passed in 1990, was especially important in increasing an interest in Green Chemistry, which is the design and redesign of chemical processes with a view of improving safety. Our group focuses on synthetic methodology i.e. the transformation of one functional group to another. Such transformations are of special relevance in the pharmaceutical industry for manufacture of life saving drugs. Many of the current organic …

A Mild And Chemoselective Method For The Deprotection Of Tert-Butyldimethylsilyl (Tbdms) Ethers Using Iron(Iii) Tosylate As A Catalyst, Ram Mohan, Jason Bothwell, Veronica Angeles, James Carolan, Margaret Olson
A Mild And Chemoselective Method For The Deprotection Of Tert-Butyldimethylsilyl (Tbdms) Ethers Using Iron(Iii) Tosylate As A Catalyst, Ram Mohan, Jason Bothwell, Veronica Angeles, James Carolan, Margaret Olson
Scholarship
The most common method for the deprotection ofTBDMS ethers utilizes stoichiometric amounts of tetrabutylammonium fluoride, n-Bu4N+F(TBAF), which is highly corrosive and toxic. We have developed a mild and chemoselective method for the deprotection ofTBDMS, TES, and TIPS ethers using iron(III) tosylate as a catalyst. Phenolic TBDMS ethers, TBDPS ethers and the BOC group are not affected under these conditions. Iron(III) tosylate is an inexpensive, commercially available, and non-corrosive reagent.
Bismuth(Iii) Bromide In Organic Synthesis. A Catalytic Method For The Allylation Of Tetrahydrofuranyl And Tetrahydropyranyl Ethers, Ram Mohan, Scott Krabbe, Veronica Angeles
Bismuth(Iii) Bromide In Organic Synthesis. A Catalytic Method For The Allylation Of Tetrahydrofuranyl And Tetrahydropyranyl Ethers, Ram Mohan, Scott Krabbe, Veronica Angeles
Scholarship
A bismuth bromide-catalyzed (10.0 mol %) multicomponent reaction involving the allylation of THF- and THP-ethers, followed by in situ derivatization with acetic anhydride to generate highly functionalized esters has been developed under solvent-free conditions. To the best of our knowledge, this is the first report of a catalytic procedure for the allylation of THF- and THP-ethers to yield ring-opened products.
Iron(Iii) Tosylate-Catalyzed Deprotection Of Aromatic Acetals In Water, Ram Mohan, Margaret Olson, James Carolan, Michael Chiodo, Phillip Lazzara
Iron(Iii) Tosylate-Catalyzed Deprotection Of Aromatic Acetals In Water, Ram Mohan, Margaret Olson, James Carolan, Michael Chiodo, Phillip Lazzara
Scholarship
The deprotection of aromatic as well as conjugated acetals and ketals in water is catalyzed by iron(III) tosylate (1.0–5.0 mol %). Iron(III) tosylate is an inexpensive and readily available catalyst. The use of water, the most environmentally benign solvent, makes this procedure especially attractive for acetal deprotection.
