Abstract

PARIHAR, J. A.  and  RAMANA, M. M. V.. Short synthesis of new 13,16-diazaestrone and 13,16-diazaequilenin analogs. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.4, pp. 881-883. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532005000500032.

Diferentes 3-[2-(3,4-diidro-1-naftil)etil]imidazolidina-2,4-dionas e 3-[2-(1-naftil)etil]- imidazolidina-2,4-dionas, quando aquecidas em ácido polifosfórico a 150 °C, sofrem ciclização quimioseletiva intramolecular resultado nos respectivos esteróides 13,16-diazaestrona e 13,16- diazaequilenina.

Keywords : polyphosphoric acid; chemoselective cyclization; 13,16-diazaestrone steroids; 13,16- diazaequilenin steroids.
