Description and Uses
(2S,3R)-(+)-N-Boc-6-oxo-2,3-diphenylmorpholine (Williams chiral auxiliary) can be used as a reactant:
- In the asymmetric synthesis of cylindrospermopsin and related alkaloids via an intramolecular 1,3-dipolar cycloaddition reaction.
- To synthesize boc-3-(1-methylcyclopropyl)-D-alanine, which is used as an intermediate to prepare 4-fluoroproline-based analogs as potent tripeptide thrombin inhibitors.
- In the total synthesis of potent hepatotoxic alkaloid 7-epicylindrospermopsin by intramolecular 1,3-dipolar cycloaddition and nitroaldol reaction.
- To prepare differentially functionalized diaminoglutamic acids via radical reaction of selenide with methyl 2-acetamidoacrylate.
