don't think so, but here are a couple of work arounds,

1. use a storage variable ( temp ) inside the object notation;

var obj={
prop1:temp="somevalue",
prop2:"another value",
prop3:{prop4:temp}
};

delete temp;        // to tidy up

if temp is an object then what you get is two references to the same
thing,

2. just add the reference outside the object notation.

var obj={
prop1:"somevalue",
prop2:"another value",
prop3:{}
};
obj.prop3.prop4=obj.prop1;

3. use getter/setter which have 'this' defined as the containing
object.

var obj={
get prop1(){return this.prop3.prop4},
set prop1(v){this.prop3.prop4=v},
prop2:"other val",
prop3:{prop4:"somevalue"}
};

.
