Sodium Borohydride-Nickel Chloride-Methanol Catalytic System for Regioselective Reduction of Electron-Rich Conjugated Dienes and Reductive Cleavage of Allyl Esters Involving π-Allylnickel Intermediates
The regioslective reduction of electron-rich dienes to monoolefins and the reductivecleavage of allyl esters were fulfilled by employing a sodium borohydride-nickel chloride-methanol catalytic system with exceedingly simple manipulations and high functional group tolerability. Both of the reductive reactions may involve π-allylnickel intermediates generated from fresh nickel boride.

The development of structural mimetics of α-helices has traditionally focused on representation of the three residues that protrude from one face of the helical surface on three consecutive turns (i.e., i, i+3/i+4, and i+7). Despite the decisive contribution these residues make to the binding interaction with protein partners, peripheral residues can play important roles particularly with regard to
