Synthesis of Homochiral Dihydroxy-4-nitroisoxazolines via One-Pot Asymmetric Dihydroxylation−Reduction
摘要:
Herein we report a one-pot procedure to prepare a family of homochiral dihydroxy-4-nitrolsoxazolines 3. This new methodology affords the title compounds in good yields, excellent enantiopurity, and without the use of chromatography.

We have investigated the reactivity of 3-methyl-4-nitro-5-styrylisoxazoles with S-nucleophiles. This study revealed that the title compounds were optimal Michael acceptors toward thiols. A procedure was also established to prepare isoxazole-containing sulfides in one-pot and without the use of chromatography. Isoxazole-containing sulfides were converted into the corresponding sulfones in high yield. (C) 2011 Elsevier Ltd. All rights reserved.
