A practical diastereoselective synthesis of β-hydroxy-β-trifluoromethyl imines
摘要:
The asymmetric carbon-carbon bond formation reaction affording chiral (3-hydroxy-(3-trifluoromethyl imines is reported involving the nucleophilic addition of sulfinimine anions derived froth chiral N-(tert-butanesulfinyl) ketimines to trifluoromethyl ketones. The reaction tolerates a wide range of nucleophiles, giving the condensation products in good to excellent total yields with good diastereoselectivities (up to 85:15 dr). (c) 2006 Elsevier Ltd.
