replacing the string of the file name and using it in the same shell script
===

I have one set of files with naming convention bond_7.LEU.CA.1.dat bond_10.VAL.CB.1.dat..... and have other set of files starting with the string distance rather than bond with the same extension i.e.,distance_7.LEU.CA.1.dat .... and i am trying to  merge corresponding or subsequent lines of files using paste command in shell scripting

I am intending to do
paste bond_7.LEU.CA.1.dat distance_7.LEU.CA.1.dat  > ../raj/angle_dist_7.LEU.CA.dat

I have tried to use for loop and stuck with replacing the string of the file name to access the appropriate file.

Thanks in advance,

Any help will be appreciated.
