TypeScript Question

typescript can't find module for system.js alias

I am working with angular2 and when I created some aliases to modules via System.js (for example)

map: {
'%cool_modules%' : prodFolderName + '/modules',

and when I tried to import {MyModule} from '%cool_modules%', I got an error about: typescript: can't find module %cool_modules%

The same for @angular/core , rx/Obserable erc.

Is it possible to fix it? Thanks

            "@angular/core": [
            "rxjs/*": [
            "systemjs": [
            "zone.js": [
            "%cool_modules%": [
