| titleOfInvention | PIRONA TYPE HETEROCICLIC COMPOUNDS AND ITS APPLICATION AS ORGANIC SUPERBASES. |
| abstract | Heterocyclic compounds type pyrone and its application as organic superbases. The present invention describes a family of heterocyclic pyrone-type compounds of high proton affinity. Generically, these compounds are formed by two or more rings that have carbonyl and ether functionalities located in different rings. The basicity of these compounds is similar to that of other "superbases" such as the so-called "proton sponges." Unlike the latter, based on amino derivatives, the heterocyclic structures of the pyrone type described in this patent are the first superbases in which the proton acceptor atom is an oxygen (carbonyl oxygen). In addition, the absence of hydrophobic groups in the vicinity of the basic center facilitates the proton transfer process. Thus, the heterocyclic structures type pyrone present a clear advantage over the current commercial superbases. |
