The boxer from Uzbekistan has the chance to fight for the gold medal after his bout against Great Britain's Frazer Clarke was stopped in the third round.
Jalolov will face Team USA's Richard Torrez Jr in the final for the gold medal. Great Britain's Frazer Clarke gets a bronze.
"It was a good fight and hopefully in the final I will be doing my best," said Jalolov. "I am aiming for the gold medal."
"I am not afraid of anybody, I am only afraid of the Creator."
World champion Jalolov had the better of Clarke, but Clarke did have his moments.
Clarke hit Jalolov with a big right hand and the Uzbek fighter took a standing count.
However, the GB boxer was unable to capitalise on this.
In the third round, the referee took the decision to stop the fight due to cuts above both of Clarke's eyes.
The cut over the GB boxer's left eye, which was caused in his last fight with Mourad Aliev, opened first. This was followed by a cut over his right eye as Jalolov caught the British boxer with some good hits.
The cuts grew worse, leading to a stoppage after the ringside doctor inspected the wounds.
Clarke was bidding to become the third successive British boxer in a row to reach the super heavyweight final.
