Sentence examples for fluorinated product from inspiring English sources

26b With the help of catalytic HFIP, the reaction proceeded smoothly at −60 °C to afford the desired fluorinated product in high yield with improved enantioselectivity.

The desired fluorinated product 48 was afforded in moderate enantioselectivities (39 55% ee) only when QN-NH2 and l-leucine were used together catalysts, and the exact function of each catalyst is unclear.

Aryl-substituted substrates all gave excellent enantioselectivities (up to 95% ee), and substrates with a longer alkyl chain and a benzyloxy-substituted compound gave the desired fluorinated product with reduced but acceptable enantioselectivity (83% ee).

While l-phenylalanine methyl ester gave −40% ee, the two chiral catalysts were evidently mismatched in this case, as switching to d-phenylalanine methyl ester gave the desired fluorinated product in 88% ee.

They found that chiral bifunctional thiourea catalyst 184 could efficiently catalyze the fluorination of β-ketoesters 35 with NFSI with the assistance of DMAP in MeOH at −60 °C to afford the desired fluorinated product in high yield with good to excellent enantioselectivities.

The authors hypothesized that an enal bearing a leaving group in γ-position would provide access to a chiral NHC-bound dienolate that may subsequently react with an electrophilic fluorinating reagent and a nucleophile to afford an enantioenriched fluorinated product (Scheme 63).

Several cyclic β-ketoesters were submitted to fluorination using NFSI and 132a (10 mol %) as catalyst, affording the desired fluorinated products 48 in high yield with moderate enantioselectivities (48 69% ee).

They don't spit, either, making fluorinated products dangerous for pets when they're swallowed.

Fluorination of γ-methyl-carbonate-substituted α,β-unsaturated enals 181 with NFSI using 183 as catalyst afforded the desired fluorinated products 182 in good yield with high enantioselectivities (Scheme 64).

As a further demonstration of the utility of this catalytic system, 3-butenoyl derivatives 45 were tested under these conditions, which gave the desired fluorinated products 46 in high yield and with good enantioselectivity (78 91% ee) (Scheme 13).

After careful optimization, it was found that catalyst 203 efficiently catalyzed the oxa-Michael addition of the substrate in toluene, after which NFSI and Na2CO3 were added into the mixture to afford the desired fluorinated flavanone product 202 in high enantioselectivities (Scheme 72).
