Macrocycle opening in crown ethers 2. Template effect in macrocycle opening in formyl derivatives of benzocrown ethers under the action of amines with the formation of podands

Article abstract of DOI:10.1007/BF01435799

Macrocycle opening in derivatives of benzocrown ethers under the action of amines is affected by the nature of the heteroatoms in the macrocycle, the nature of the functional group in the benzene ring of the crown ether, and the length, branching, and num
