Lithium ester enolates, prepared by the reaction of lithium N-isopropylcyclohexylamide (LIICA) with esters at -78' (eq. 1); react with acid chlorides at this same low temperature to provide satisfactory yields of the corresponding S-keto esters (eq. II). This procedure represents an exceedingly vers

## Swnmary: T-butyl 2,2,2-trichloroaceiimi&e (l), reaa?ly prepared by addition of t-butawl to trichloroacetonitrile, is an efficient reagent for the preparation of t-butyl ethers and esters in the presence of a catalytic amount of boron trifhon& etherate. Traditional methods for the preparation of
Resin bound peptides can be cleaved from the Kaiser oxime resin using various oxygen nucleophiles (H20, CH3OH, PhCH2OH) with DBU. Fully protected peptide acids and esters are obtained rapidly and with good yields using this new method of cleavage.
