Identifying a zero-range exchange of vector mesons as the driving force for the s-wave scattering of pseudo-scalar mesons off the baryon ground states, a rich spectrum of molecules is formed. We argue that chiral symmetry and large-Nc considerations determine that part of the interaction which generates the spectrum. A bound state with exotic quantum numbers is predicted at mass 2.78 GeV. It couples strongly to the (DˉsN),(DˉΛ),(DˉΣ)

channels. A further charm minus-one system is predicted at mass 2.84 GeV as a result of
(DˉsΛ),(DˉΞ)
interactions. The two so far observed s-wave baryons with charm one are recovered. We argue that the
Λc(2880)
is not a s-wave state. In addition to those states we predict the existence of about ten narrow s-wave baryon states with masses below 3 GeV. A triplet of crypto-exotic states decaying dominantly into channels with an
