- Process for preparing alicyclic carboxylic acid compounds
-
A process for preparing at least one alicyclic carboxylic acid compound by Grignard reaction, the process comprising: reacting magnesium and at least one alicyclic halide compound in at least one solvent to produce at least one alicyclic Grignard reagent;concurrently adding carbon dioxide to the magnesium, the alicyclic halide compound, the solvent, and the alicyclic Grignard reagent, while the alicyclic Grignard reagent is still being produced, to form at least one alicyclic carboxylate magnesium salt; andhydrolyzing the alicyclic carboxylate magnesium salt to form the alicyclic carboxylic acid compound;wherein the alicyclic Grignard reagent and the alicyclic carboxylate magnesium salt are prepared in a one-pot synthesis.

- Metal Alkoxide Modified Organometallic Reagents. Preparation and Stability of Organolithium Reagents in Tetrahydrofuran in the Presence of Magnesium 2-Ethoxyethoxide
-
The metalating ability of alkyllithium reagents and their tendency to cleave THF are greatly diminished in the presence of magnesium 2-ethoxyethoxide, 1.Advantage may be taken of this to generate organolithium reagents in THF in the presence of 1 under conditions not normally favorable to their stability.Thus, by reaction with metallic lithium in the presence of 1 in THF, the compounds RX (R = n-Bu, s-Bu, t-Bu, cyclohexyl, menthyl, p-methoxyphenyl, o-(methoxymethyl)phenyl; X = Cl, Br) have been converted to the corresponding organometallic reagents.In the absence of 1 the alkyllithium reagents formed react with the solvent, resulting in reduced yields and often alternative products.In the case of the preparation of the arylmetal reagents the presence of 1 suppresses either subsequent orthometalation (R = p-methoxyphenyl) or Wittig rearrangement (R = o-(methoxymethyl)phenyl) to give a clean replacement of halogen by the metal.The presence of THF is also tolerated in the preparation of these two arylmetal reagents by halogen-metal exchange using n-butyllithium in the presence of 1 whereas if 1 is absent little or none of the desired product is obtained.

- Synthesis of N-t-butyl-p-menthane-3-carboxamide
-
This invention provides an efficient two-step reaction sequence for producing N-t-butyl-p-menthane-3-carboxamide. The process involves forming 3-p-menthylmagnesium halide, and reacting the 3-p-menthylmagnesium halide with t-butyl isocyanate to form the product.
