Typecasting a class pointer

I've got a code that is the following way:

classes.h
class claseA {
     public:
         claseA();
         ~claseA();
};

class claseB {
     public:
         claseB();
         claseB( const claseA& aClase);
         ~claseB();
};

main.cpp
#include "classes.h"

int main () {
    claseA* pClaseA = new claseA();
    claseB* pClaseB = new claseB( pClaseA* ); // compiler error

.....

    return 0;
};

I get a "expected primary-expression before ')'" error at the marked
line. Seems that try pass a class using a pointer is not valid but when
I try to typecast the dereferenced pointer this way:

classB* pClaseB = new claseB( (claseA)pClaseA* );

I get a different compiler error: "no matching function call to
'claseA::claseA(claseA*&)'

In case this compiler error is a precedence error I tried too the
following code line:

classB* pClaseB = new claseB( (claseA)(pClaseA*) );

but I get again the first compiler error: expected primary-expression
before ')'

Is clear that I'm missing something, or is just that cannot be done this
way?
