I have subclassed develop command:

class develop(develop):
    sub_commands = [('compile_catalog', None)] + develop.sub_commands

cmdclass = dict(build=build, develop=develop),

However compile_catalog is not called.

Thanks, this seems a good solution.
I think I will use this.

Note however that the configuration group is "aliases", not "alias".

It is unfortunate that aliases are not executed internally.
That is, I would really like to define an alias for the "build" command,
and have it expanded when "build" command is called by other commands
like "bdist".

In my case this is not a problem, but I prefer to generate them during
setup, if this is not inconvenient.
