A series of some new Pregnenolone derivatives have been synthesized by McMurry reaction which include using of (Low-Valent) titanium from (TiCl 4 ) with (Zn-dust) as catalyst and (THF) as a solvent to convert the (ketonic carbonyl group) of Pregnenolone with a new aldehyde or ketone compound to a new aliphatic double bond connected each other. All the new synthesized derivatives were monitored by (TLC) and assigned by elemental analysis, melting points, FT-IR and ( 1 H NMR,  13 C NMR and 2D-NMR) spectroscopy. The anti-bacterial and anti-fungi activity of these derivatives were also determined.
