The first synthesis of a derivative of cyclo(d-Pro-l-Pro-d-Pro-l-Pro) is reported. The convergent route to the molecule is amenable to the synthesis of gram quantities of the desired compound. The cyclization of the linear tetramer was found to give specifically one conformation of the 12 member macrocycle. The structural assignment, by 2D NMR, of the favored conformation is also reported.
报道了环(d-Pro-1-Pro-d-Pro-1-Pro)的衍生物的第一合成。到达分子的收敛途径适合于合成克量的所需化合物。发现线性四聚体的环化特别地给出了12元大环的一种构象。还报道了通过2D NMR的有利构象的结构分配。
