in the synthesis of more complex compounds. Herein, we report a simple and convenient one-pot strategy to synthesize functionalized carbonyl compounds starting from these readily available substrates, via tandem or one-pot hydroformylation, Michael addition, and aldol reactions. The combination of various reactions in one operational step leads to many advantages in synthetic strategies, such as a lower
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

guanidine is found to function as an effective platform for asymmetric induction at the alpha-carbon of unsymmetrically substituted 1,3-dicarbonyl compounds. Highly efficient and enantioselective electrophilicamination of various 1,3-dicarbonyl compounds with azodicarboxylate was successfully achieved using the present chiral guanidine catalyst, which provides efficient access to the construction of
