Are you accessing the sites from a university or somesuch? I checked all the Eur. J. Org. Chem. volumes (1998-2003), and they all required login or a $25 payment per article to grant access. They will only allow access to Issue #1 (2003) for people who have registered with them (when registering, you get one sample issue of each Wiley Journal, it's not much, but it's free).
