One‐Pot Synthesis of α‐Formyloxy Ketones from Enolizable Ketones
摘要:
One-pot synthesis of alpha-formyloxy tones as well as alpha-acetoxy ketones from enolizable ketones and [hydroxy(tosyloxy)iodo] benzene (HTIB)/polymer supported [hydroxy(tosyloxy)iodo]benzene (PSHTIB) in N,N - dimethylformamide (DMF)/N,N - dimethylacetamide (DMA) in high yields is described.
A sustainable byproduct catalyzed domino strategy: facile synthesis of α-formyloxy and acetoxy ketones via iodination/nucleophilic substitution/hydrolyzation/oxidation sequences
The sustainable byproduct catalyzed domino strategy has been performed for the facilesynthesis of alpha-formyloxy and acetoxy ketones via iodination/nucleophilic substitution/hydrolyzation/oxidation sequences from simple and readily available aromatic ketones/unsaturated methyl ketones.
