The relative and absolute stereochemistry of amphidinoketide I has been determined by the total synthesis of all the diastereoisomers. Molecular modelling suggests that the natural product is not the thermodynamically preferred diastereoisomer.
The divergent syntheses of the trichloroacetamide derivatives of (2S,3R,8R,9R,4E,6E)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-decadenoic acid (enantio-iso-ADDA), and (2R,3R,8R,9R,4E,6E)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-decadenoic acid (enantio-ADDA), have been achieved. Our approach takes advantage of highly efficient non-aldol aldol, palladium catalysed aza-Claisen and cross-metathesis
We established a facile access to an unexplored mirror-image library of chiral natural product derivatives using D-protein technology. In this process, two chemical syntheses of mirror-image substances including a target...
The synthesis of the C13-C23 segment of tedanolide is described making use of orthogonal protecting groups in the construction of the carbon skeleton and for the selective liberation of hydroxyl groups in the endgame of the total synthesis.
