I think current theories are that the 5 AU point, where Jupiter
now resides, was the location in the protoplanetary disk where the
ambient temperature of the dust and gas was at the ice point of water.
The slush in that zone quickly accreted matter forming proto-Jupiter
first among the planetesimals.
In a runaway process, this quickly depleted a zone of matter and starved
the region of the asteroid belt of matter - hence no planet there.
Similar slush points farther out at 10 and 20 AU (where I think
ammonia and methane formed ice) created Saturn and Uranus a little later.
