Stoichiometric mixtures of carboxylic acids and primary or secondary alkyl alcohols are cleanly converted into their corresponding esters by treatment with di-t-butyl dicarbonate [(BOC) 2 O] in the presence of catalytic amounts of N,N'-dimethylaminopyridine (DMAP). This convenient procedure provides a general access to a broad variety of esters including those bearing highly sensitive functional groups
Direct and Selective Syntheses of α,α-Dichloroethyl Ketones or Their Ethyl Trimethylsilyl Mixed Acetals by the Reactions of Methoxymethyl or Ethyl Carboxylates with 1,1-Dichloroethyllithium in the Presence of Chlorotrimethylsilane
generated by treating 1,1-dichloroethane (2) with lithium diisopropylamide (LDA) or n-butyllithium, reacted with methoxymethyl carboxylates in the coexistence of chlorotrimethylsilane (3) to afford the corresponding α,α-dichloroethyl ketones in good yields. On the other hand, 1 reacted with ethyl carboxylates under the above reaction conditions to give 2,2-dichloro-1-alkyl-1-ethoxy-1-(trimethylsiloxy)propanes
