We report a highly enantioselective [3C + 2C] intramol. cycloaddition of alkylidenecyclopropanes (ACPs) and alkenes. The best results are obtained by using sterically demanding chiral phosphoramidite ligands derived from Vapol. Moreover, we also show that related, but less bulky, phosphoramidites can also lead to very effective [4C + 3C] cycloadditions when dienes, instead of alkenes, are used as reacting partners. The reactions provide a practical, simple, and selective access to optically active, synthetically appealing 5,5- and 5,7-bicyclic systems. This study involved multiple reactions and reactants, such as (R)-[1,3′:1′,1”:3”,1”’-Quaternaphthalene]-2′,2”-diol (cas: 851615-07-1Product Details of 851615-07-1).
(R)-[1,3′:1′,1”:3”,1”’-Quaternaphthalene]-2′,2”-diol (cas: 851615-07-1) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Product Details of 851615-07-1
