Tin(IV) ion-exchanged montmorillonite (Sn-Mont) was found to be an excellent solid acid catalyst for the Mukaiyama aldol reactions of congested ketones with silicon enolates from ketones as well as esters. It was disclosed that Sn-Mont was far more active than other metal ion-or proton-exchanged montmorillonites and typical homogeneous acid catalysts such as TMSOTf and BF3?OEt2.

A convenient two step protocol preparation of the ortho-alkylated (by secondary substituent with the carbomethoxy group at the end of alkyl chain) aromatic carboxylic acids 6 from benzoic acids anilides 1 was developed, which exploited the reductive alkylation of phthalides 4 with silyl vinyl ethers 5a-b or silyl ketene acetals 5c-g as a key step, is described.

The action of zinc powder with α-bromoesters in the presence of trimethylsilylchloride and TMEDA-Et3N led mainly to E-ketenealkylsilylacetals while the reaction of trialkylsilanes on alkyl acrylates catalyzed by Wilkinson reagent gave stereoselectively th
