So it's just an implausible buzz.Ondes Martenot wrote:I'm not sure how the first clue affects things, but it seems like crown ethers could have been accepted after template effect.
(I don't think "macrocyclic" comes too early; it doesn't give any special information to me. I could be totally wrong.)
