Synthesis of new alkyl derivatives of 2,2 '-dihydroxy-1,1 '-binaphthyl

2'-Hydroxy-1,1'-binaphthyl-2-yl phosphate 4 reacts with various alkylating agents under controlled conditions to give differently alkylated phosphoric esters 5-9. The monoalkylation of binaphthol 1 with long-chain alkyl halid es followed by reaction with phosphoryl chloride, propane-13-sultone or chl orosulfuric acid, respectively, yielded the amphiphilic binaphthyl derivati ves 14-17. The compounds prepared were fully characterized by spectroscopic methods.
