Synthesis of 4-carboethoxy-4-oxazolin-2-ones from 3-nosyloxy-2-ketoesters
摘要:
3-Nosyloxy-2-ketoesters, available from 2-ketoesters, react efficiently with methyl carbamate and tosic acid in refluxing toluene to provide 4-carboalkoxy-4-oxazolin-2-ones in good yields (41-84%). (C) 1998 Elsevier Science Ltd. All rights reserved.

Skyllamycin is a non‐ribosomally synthesized cyclic depsipeptide from Streptomyces sp. Acta2897 that inhibits PDGF‐signaling. The peptide scaffold contains an N‐terminal cinnamoyl moiety, a β‐methylation of aspartic acid, three β‐hydroxylated amino acids and one rarely occurring α‐hydroxy glycine. With the exception of α‐hydroxy glycine, the stereochemistry of the amino acids was assigned by comparison

An efficient three-step methodology developed for the preparation of 1,2-amino alcohols. In the first step a rapid coupling between bromoketones and potassium phthalimide in ionic liquid produced alpha-phthalimido ketones in quantitative yields, which is followed by a facile reduction using NaCNBH3 in acetic acid to give corresponding phthalimido alcohols and finally effecting hydrazinolysis in water at 60 degrees C to yield biologically important 1,2-amino alcohols.
