Zusammenfassung: | Pyrone type heterocyclic compounds can be applied as organic super bases with high protonic affinity. Generically, the compounds are formed by two or more rings, which present carbonyl and ether functions situated in different rings. The basicity of the compounds is similar to that of other super bases like those denominated as protonic sponges. Different to the latter, based on aminated derivatives, the pyrone type heterocyclic compounds are the first super bases in which the atom acceptor of protons is an oxygen (carbonylic oxygen).

Compuestos heterocíclicos tipo pirona y su aplicación como superbases orgánicas. La presente invención describe una familia de compuestos heterocíclicos tipo pirona de elevada afinidad protónica. Genéricamente, estos compuestos están formados por dos o más anillos que presentan funcionalidades carbonilo y éter situadas en diferentes anillos. La basicidad de estos compuestos es similar a la de otras "superbases" como las denominadas "esponjas protónicas". A diferencia de estas últimas, basadas en derivados aminados, las estructuras heterocíclicas tipo pirona descritas en esta patenta son las primeras superbases en las que el átomo aceptor de protones es un oxígeno (el oxígeno carbonílico). Además, la ausencia de grupos hidrófobos en las proximidades del centro básico facilita el proceso de transferencia protónica. Así pues, las estructuras heterocíclicas tipo pirona presentan una clara ventaja sobre las superbases comerciales actuales. |
