A facile approach to tryptophan derivatives for the total synthesis of argyrin analogues [PDF]
, 2014 A facile route has been established for the synthesis of indole-substituted (S)-tryptophans from corresponding indoles, which utilizes a chiral auxiliary-facilitated Strecker amino acid synthesis strategy. The chiral auxiliary reagents evaluated were (S)-

Supramolecular Gels as Active Tools for Reaction Engineering
Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and
