Lithiation Experimental Procedure

The reaction of lithiated S,S-acetals with aldehydes and ketones is a well-established reaction and needs no exemplification by an experimental procedure. The reactions with most of the aldehydes and ketones are extremely rapid, even at temperatures in the region of — 80 °C. A number of examples have been mentioned in the reviews of Seebach [1,2]. [Pg.66]

Modification of the experimental procedure used for the previous ortho lithiation strategies was necessary for the preparation of trifluoromethyl- and trifluoro-mefhoxy-substituted benzenesulfonyl chlorides. When 3-trifluoromethylanisole (24, PG = Me, Scheme 6) was subjected to conditions identical to those in... [Pg.92]
