var a = function () {
    var obj = $.Deferred();
    setTimeout(function () {
      console.log('resolving a');
      obj.resolve({a: 1});
    }, 1000);
    return obj;
}
    
var b = function () {
    var obj = $.Deferred();
    setTimeout(function () {
      console.log('resolving b');
      obj.resolve({b: 2});
     }, 2000);
    return obj;
}
    
var c = function () {
    var obj = $.Deferred();
    setTimeout(function () {
      console.log("resolving c");
      obj.resolve({c: 3});
    }, 3000);
    return obj;
}

$.when(c()).pipe(b).then(a);
// resolving c
// resolving b
// resolving a
