Expedient and Diastereodivergent Assembly of Terpenoid Decalin Subunits having Quaternary Stereocenters through Organocatalytic Robinson Annulation of Nazarov Reagent
report an expedient approach to highly functionalized cis‐ and trans‐decalines that could function as key structural subunits toward the synthesis of various classes of terpenoids. Key to the strategy is an organocatalyzed Robinsonannulation reaction of the Nazarovreagent that affords chiral enone building blocks with high enantioselectivities. The quaternary carbon stereogenic center can direct the subsequent
1,1′-Biphenyl-2,2′-diphosphines having at least one amine substituent in the para position relative to the phosphine group and having the formulae
are ligands for metal complexes which serve as catalysts for asymmetric addition reactions of prochiral organic compounds and whose catalytic properties can be tailored specifically to particular substrates by substitution of the amine group.
