Marc Feeley is a pretty cool guy: in addition to developing the full Scheme system Gambit-C (http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/Main_P...), with others he's done a variety of smaller useful systems, some of which you can find in the Gambit-C Wiki's Dumping Grounds http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/Dumpin...:

Jss: JavaScriptScheme: a multithreaded Scheme to JavaScript compiler

PICOBIT: Very compact Scheme compiler and virtual machine suitable for microcontrollers

While there are of course many Scheme to Javascript systems (easy because Javascript is mostly "Scheme with an ALGOL face") I know the latter has been used in some serious projects.

Scheme->JavaScript isn't that easy, because of tail calls. But Jss handles it.
