An improved method for the synthesis of Fmoc-N-methyl serine and threonine has been developed, which involves formation and subsequent reduction of the corresponding oxazolidinone with a Lewis acid under mild conditions, with improved yields and shorter reaction times.
Auyuittuqamides A-D, Cyclic Decapeptides from Sesquicillium microsporum RKAG 186 Isolated from Frobisher Bay Sediment

Four new cyclic decapeptides, auyuittuqamides A-D (1-4), were obtained from Sesquicillium microsporum RKAG 186 obtained from marine sediment collected from the intertidal zone of Frobisher Bay, Nunavut, Canada. The structures of the compounds were elucida
Synthesis, stereochemical assignment, and bioactivity of the Penicillium metabolites penicillenols B1 and B2

The Penicillium metabolites penicillenols B1 and B2 were synthesised for the first time by elimination of a mesylated penicillenol A precursor as obtained from an l-threonine derived tetramic acid. The (Z,S)- and (E,S)-configured diastereomers were identical to the natural compounds as to NMR spectra and optical rotations. Both isomers showed antiproliferative effects against cancer and endothelial cell lines and penicillenol B1 was also notably antibiotic against Staphylococcus aureus.
Solid-Phase Total Synthesis of the Proposed Structure of Coibamide A and Its Derivative: Highly Methylated Cyclic Depsipeptides
Sable, Ganesh A.,Park, Jaekwan,Kim, Hyunsik,Lim, Soo-Jeong,Jang, Soonmin,Lim, Dongyeol

The solid-phase total synthesis of the proposed structure of cyclic depsipeptide coibamide A and its derivative O-desmethyl coibamide A is reported. In this study, we demonstrate the solid-phase synthetic strategy and final solution-phase O-methylation fo
