Abstract
Se proveen beta-sulfonamida alfa-cetoésteres y amidas en los cuales el alfa-ceto es protegido corno un derivado de 1,3-ditiolano. También se proveen métodos para preparar dichos ésteres y amidas y para incorporarlos en los péptidos. Reivindicacion 1: Un método para preparar un beta-sulfonamida alfa-cetoéster de la formula (1) o (2) en donde cada uno de R1 y R3 es independientemente alquilo o arilo; y R2 es alquilo, cicloalquilo, cicloalquilalquilo, alquenilo, arilo, o heterocicloalquilo enlazados al átomo de carbono C* en un anillo de átomo de carbono, que comprende el paso de mezclar una sulfinimina de la formula (3) o (4), con un éster carboxilato de ditiolano de la formula (5) en presencia de una base de fuerza suficiente para desprotonar el hidrogeno de ditiolano de la formula (5), en donde R1 y R2 en la formula (3) y (4) y R3 en la formula (5) son como se definieron con antelacion, para formar un beta-sulfonamida alfa-cetoéster de la formula (1) o (2). Reivindicacion 36: Un compuesto de la formula 6, formula 7, o formula 8 en donde cada uno de R1 y R3 es independientemente alquilo o arilo, R2 es alquilo, cicloalquilo, cicloalquilalquilo, alquenilo, arilo o heterocicloalquilo; y R4 es hidrogeno, alquilo, cicloalquilo o arilo.
