Contribution of the O-benzoyl groups of tetra-O-benzoyl-α,β-l-arabinopyranoses to the formation of 1,1-bis(benzamido)-1-deoxy-l-arabinitol

Several 1,2,3,4-tetra-O-benzoyl-l-arabinopyranoses selectively labeled with C6H5[14C]CO groups at different positions were synthesized. Their reactions with methanolic ammonia afforded a labeled 1,1-bis(benzamido)-1-deoxy-l-arabinitol (18). The contribution of each benzoyl group to the formation of...
