no.  unless tcsh implements regexp's *really* weird, that means a
string beginning with foo, contains any number of chars for a while,
and then has a char that is neither r or e, and then the last char is c.
so the following starred files would be listed in your example:

* foo2c
  fooec
  foorc
  foo2.rec
  fooc

in reality what you should really use is grep:

    ls foo*c | grep -v 'rec$'

unless you're using something like zsh, i don't thing filename expansion
regular expressions are the way to go.  here it is in zsh - might work
in other shells:

    ls (foo(|?|??)c|foo*([^.][^r][^e]|.[^r][^e]|[^.]r[^e]|[^.][^r]e|.r[^e]|.[^r]e|[^.]re)c)

which lists the following files (but not foo2.rec):

    foo2.rrc  foo2c  fooc  fooec  foorc
