Studies toward Australifungin. A Synthesis Dilemma of Regioselective Keto–Enol Tautomerization

19-Jan-2016 | David R. Williams; J. Cullen Klein; Lucas C. Kopel; Nhu Nguyen; Dean J. Tantillo, Organic Letters, 2016

Studies have advanced a stereocontrolled pathway for the synthesis of australifungin. Elaboration of the trans-fused IMDA product 4 led to the cis-diol 15, which produced the α-hydroxyenone 19 upon oxidation. Computational studies on model systems indicate that the keto–enol tautomer shown for 19 ...

Medusamide A, a Panamanian Cyanobacterial Depsipeptide with Multiple β-Amino Acids

19-Jan-2016 | Amanda M. Fenner; Niclas Engene; Carmenza Spadafora; William H. Gerwick; Marcy J. Balunas, Organic Letters, 2016

From a collection of marine cyanobacteria made in the Coiba National Park along the Pacific coast of the Republic of Panama a novel cyclic depsipeptide, given the trivial name medusamide A, has been isolated and fully characterized. Medusamide A contains four contiguous β-amino acid ...
