| titleOfInvention | Orthoester derivatives of crown ethers as carriers for pharmaceutical and diagnostic compositions |
| abstract | This invention relates to A crown ether of formula (I) n n n n n n n n n n wherein m is 4, 5, 6, 7, or 8 and i is, independently for each occurrence, 1 or 2; each occurrence of R 1 and R 2 is independently selected from hydrogen; linear or branched and substituted or unsubstituted C 1 to C 10 alkyl, alkenyl and alkinyl; and substituted or unsubstituted aryl with up to 10 ring atoms; or R 1 and R 2 together form an oxo group; at least one occurrence in the crown ether of R 1 , R 2 and the carbon to which R 1 and R 2 are attached, said carbon being bound directly to an ether oxygen of formula (I), form together a group of formula (II) n n n n n n n n n n wherein L is a linker which is absent or selected from a covalent bond and (CR 5 R 6 ) n , each occurrence of R 5 and R 6 being independently selected from hydrogen; linear or branched and substituted or unsubstituted C 1 to C 10 alkyl, alkenyl and alkinyl; and substituted or unsubstituted aryl with up to 10 ring atoms, n being 1, 2 or 3; X and Y, independently from each other, are selected from O and S; Z, independently for each occurrence, is absent or an electron-withdrawing group; R 3 and R 4 , independently for each occurrence, are selected from hydrogen; linear or branched and substituted or unsubstituted C 1 to C 10 alkyl, alkenyl and alkinyl; substituted or unsubstituted aryl with up to 10 ring atoms; H(OCH 2 CH 2 ) k - and H(OCH 2 CH 2 ) k O—, wherein k is an integer number from 1 to 10; wherein substituents, if present, are selected from OH, O—CH 3 and halogens. |
