A magnesium-catalyzed regiodivergent C-O bond cleavage protocol is presented. Readily available magnesium catalysts achieve the selective hydroboration of a wide range of epoxides and oxetanes yielding secondary and tertiary alcohols in excellent yields and regioselectivities. Experimental mechanistic investigations and DFT calculations provide insight into the unexpected regiodivergence and explain the different mechanisms of the C-O bond activation and product formation.

A novel synthesis of the promising optically pure chiral (4R)-4-methylpentanolide that is based on several regiospecific oxidative transformations of (4R)-2,4-dimethyl-1-(1-methylethyl)-1-cyclohexene, the product of addition of (-)-menthone and methylmagn
Synthesis of chiral calix[n]arenes - I. A synthetic approach towards a new enantiomerically pure calix[8]arene derivative
Jauch, Johann,Schurig, Volker
, p. 169 - 172 (2007/10/03)
The first epc-synthesis of a chiral calix[8]arene starting from (-)-menthone is described. In a three step sequence a new enantiomerically pure calix[8]arene derivative is obtained in good yield.
