title: Methyl N,N-diallyl-O-tert-butyltyrosyl-alpha-aminoisobutyrl-alpha- aminoisobutyrate, C28H43N3O5.
abstract: In this N- and C-protected tripeptide the nine back-bone atoms are essentially planar and fully extended except for N1 and C3' which lie below the plane and are folded in towards it. The tyrosine side chain extends away from the opposite side of the plane. There is one (N-H)i ... (O = C)i intramolecular hydrogen bond and a weak (N-H)i+2 ... (O = C)i intermolecular hydrogen bond [where (i) = 2].
