  DOTA-tris(OPp ester) as a bifunctional prochelator for the preparation of DOTA–peptide conjugates

  摘要：

  Peptides containing the chelator DOTA have gained importance for molecular imaging and therapy with radionuclides. However, all synthons described for the convergent solid phase synthesis of DOTA-peptide conjugates show windows of stability that are too narrow to allow a clean and convergent deprotection process. The synthesis of the new prochelator DOTA-tris(OPp ester) starting from cyclen is reported. Using this prochelator for the synthesis of several DOTA peptide conjugates revealed that its cleavage-in contrast to the cleavage of DOTA-tris(tBu ester) conjugates-does not require an extended deprotection time, and therefore results in clean and homogenous products.

  using pulsed electron–electron double resonance (PELDOR or DEER) at high fields/frequencies. For certain complexes, particularly those with relatively small zero‐field splitting (ZFS) and short distances between the two metal centers, the pseudosecular term of the dipolar coupling Hamiltonian is non‐negligible. However, in general, the contribution from this term during conventional data analysis is

• Cumyl Ester as the C-Terminal Protecting Group in the Enantioselective Alkylation of Glycine Benzophenone Imine
  作者：Tomasz Respondek、Eric Cueny、Jeremy J. Kodanko

  DOI：10.1021/ol202939g

  日期：2012.1.6

  Cumyl ester is an optimal C-terminal protecting group for glycine benzophenone imine in asymmetric alkylation reactions catalyzed by Cinchona chiral phase-transfer catalysts. High levels of enantioselectivity have been obtained (up to 94% ee) with this substrate, which provides an attractive alternative to the analogous tert-butyl ester. N-terminal imines and the C-terminal esters can be cleaved from
