Zampella, Angela published the artcileStereoselective synthesis of (2R,3R,4R)-3-hydroxy-2,4,6-trimethylheptanoic acid and determination of the absolute stereochemistry of the natural product from callipeltin A, Quality Control of 99438-28-5, the publication is Tetrahedron: Asymmetry (2002), 13(12), 1237-1239, database is CAplus.
A revised stereostructure of 3-hydroxy-2,4,6-trimethylheptanoic acid, the β-hydroxy acid that acylates the N-terminus of callipeltin A, is proposed on the basis of anal. of J-coupling in the 1H NMR spectrum of the acetonide derivative obtained from the acid hydrolyzate of callipeltin A. The proposed structure was definitively confirmed by enantioselective synthesis.
