A simple, direct one-pot organocatalytic approach to the formation of optically active propargylic fluorides is presented. The approach is based on organocatalytic a-fluorination of aldehydes and trapping and homologation of the intermediate providing optically active propargylic fluorides in good yields and enantioselectivities up to 99% ee. The procedure takes place by addition of NFSI, in the presence of 2-[bis(3,5-bis-trifluoromethylphenyl)trimethylsilyloxymethyl]pyrrolidine (as low as 0.25 mol %) as the catalyst, to aldehydes in combination with dimethyl 2-oxopropylphosphonate and 4-acetamidobenzenesulfonyl azide. The scope of the reaction is demonstrated by the formation of a number of optically active propargylic fluorides. It is also shown that optically active fluoro-containing triazoles can be obtained in one-pot procedures from aldehydes using click-chemistry. Furthermore, important coupling and multicomponent reactions of the optically active propargylic fluorides can be performed without affecting the enantiomeric excess. The direct one-pot formation of optically active allylic fluorides from aldehydes is also demonstrated. Finally, the mechanisms for both the formation of the propargylic and allylic fluorides are outlined.
