Semipermanent C-Terminal Carboxylic Acid Protecting Group: Application to Solubilizing Peptides and Fragment Condensation

29-Dec-2014 | Marta Paradís-Bas; Judit Tulla-Puche; Fernando Albericio, Organic Letters, 2014

The 2-methoxy-4-methylsulfinylbenzyl alcohol (Mmsb-OH) safety-catch linker has been described as a useful tool to overcome two obstacles in peptide synthesis: the solubility and fragment condensation of peptides. The incorporation of the linker into an insoluble peptide target, thereby allowing ...

A Concise Total Synthesis of Breitfussin A and B

16-Dec-2014 | Sunil Kumar Pandey; Yngve Guttormsen; Bengt Erik Haug; Christian Hedberg; Annette Bayer, Organic Letters, 2014

The first total synthesis of breitfussin A and B is described. The approach features two palladium-catalyzed cross-couplings installing the indole and pyrrole onto the oxazole core and selective lithiation/iodination of a common indole–oxazole fragment providing 2,4-diiodinated or 2-iodinated ...

One-Pot Protocol to Functionalized Benzopyrrolizidine Catalyzed Successively by Rh2(OAc)4 and Cu(OTf)2: A Transition Metal–Lewis Acid Catalysis Relay

12-Dec-2014 | Hua-Dong Xu; Zhi-Hong Jia; Ke Xu; Hao Zhou; Mei-Hua Shen, Organic Letters, 2014

4-N-Allylarylpropylamino-1-sulfonyl triazoles are converted to structurally unique benzopyrrolizidinyl sulfonamides in a one-pot operation. Intramolecular capture of rhodium carbene with arylamino nitrogen gives rise to the formation of an ammonium ylide immediate. A [2,3]- or [1,2]-rearrangement ...
