NAHAR, L.; TURNER, A. B.  y  SARKER, S. D.. Synthesis of hydroxy acids of dinorcholane and 5β-cholane. J. Braz. Chem. Soc. [online]. 2009, vol.20, n.1, pp. 88-92. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532009000100015.

A diastereomeric mixture (55:45) of 3-oxo-23,24-dinorchol-4-en-22-hydroxy acids (4A and 4B) was synthesized from 3-oxo-23,24-dinorchol-4-en-22-al (1) in 3 steps. Similarly, 3-oxo-5β-cholane-24-hydroxy acid (9) was synthesized from 5β-cholane-3α,24-diol (5) in 4 steps. Full spectroscopic data for these compounds are presented.

Palabras llave : 3-oxo-23,24-dinorchol-4-en-22-al; 3-oxo-5β-cholane-24-al; cyanohydrin silyl ether; hydroxy acid; NMR.
