Recessive is Dominant to Dominant?
Dominance by silencing the other allele

The mechanisms by which dominance work are still very much unknown. One type of mechanism that will be of particular interest to this question is the modifier of dominance where the protein product of an allele silence the expression of the other allele in order to cause dominance relationship.

Is the pattern you describe possible?

In such system, I can imagine a case where allele A1 would silence A2 which would silence A3 which would silence A1. I can't think of any reason such a pattern should not exist. However, I am not aware of evidence of such pattern. 

The interesting case of SI in Arabidopsis thaliana

This type of dominance (dominance through silencing the other allele) has been reported in the self-incomtability locus of Arabidospsis theliana (Durand et al. 2014). At this specific locus there are 6 alleles but they have a very hierchical relationship where A1 silences all other alleles, A2 silences all alleles but A1, A3 silences all other alleles but A1 and A2 etc..
