You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.140924-50-1, Name is (Dhq)2phal, molecular formula is C48H54N6O4. In a patent, introducing its new discovery.
(2R,3R,4S)-4-Amino-2,3-dihydroxyheptane-1,7-dioic acid, a common component of cyclic depsipeptide homophymines with anti-HIV activity, was synthesized as its orthogonally protected derivative from Fmoc-Glu(t-Bu)-OH in 6 steps. Osmium-catalyzed dihydroxylation of gamma-amino-Z-alpha,beta-unsaturated esters gave the dihydroxy esters with moderate diastereoselectivity. The stereochemistries of the amino acidswere determined by comparison of 1H NMR spectra.
