A short and efficient synthesis of (R,R)-2-methylcyclopropanecarboxylic acid

supporting information, p. 689 - 692 (2012/12/29)
We report herein a short and efficient synthesis of (R,R)-2- methylcyclopropanecarboxylic acid via a Horner-Wadsworth-Emmons reaction involving commercially available (S)-propylene oxide and triethylphosphonoacetate (TEPA). The TEPA/base/propylene oxide stoichiometry was found critical to achieve high yields. We therefore studied the TEPA anion formation and stability using in situ IR spectroscopy. The reaction yield is strongly influenced by the counterion and solvent, whereas high diastereoselectivities are always obtained. Under the best experimental conditions (HexLi/MeTHF/150 °C), crude (R,R)-2-methylcyclopropanecarboxylic acid is obtained in 85-90% yield with >98% trans selectivity.

A series of α,β-unsaturated carboxylic acids derivatized with camphorsultam 1 a s a chiral auxiliary has been stereoselectively cyclopropanated. the selectivity of the reaction produces cyclopropanated products with the 1R,2R absolute configuration as indicated by the optical rotations as well as by an X-ray structure determineation.The temperature dependence of the reaction was studied with three substrates. the highest stereoselectivity was obtained at temperatures above 25 deg C.Branching at the α- or β-carbons disfavours complete conversion, and electron-withdrawing substituents at these positions seem to prevent the reaction.The auxiliary was removed by using titanium(IV) isopropoxide in benzyl alcohol followed by alkaline hydrolysis of the intermediate ester. the potent 5-HT1A receptor agonist (1R,2S)-2-(2-hydroxyphenyl)-N,N-dipropylcyclopropylamine 13 was synthesized by this method
