Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of formulae Ia and Ib are constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. These macrocycles Ia and Ib are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being the agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), ion channels and signal transduction pathways. In particular, these macrocycles act as antagonists of the motilin receptor, the FP receptor and the purinergic receptors P2Y

1.3 and as inhibitors of the β-catenin-dependent “canonical” Wnt pathway. Thus they are showing great potential as medicaments for a variety of diseases.
Compounds of formula (I), in which R1, R2 and R3 are as defined in claim 1, are
particularly suitable as herbicides.

Hexafluoroisopropanol: a powerful solvent for the hydrogenation of indole derivatives. Selective access to tetrahydroindoles or cis-fused octahydroindoles
作者:Damien Clarisse、Bernard Fenet、Fabienne Fache
DOI:10.1039/c2ob25980j
日期:——
Pd/C in HFIP was used to hydrogenate indole derivatives under relatively mild conditions, leading to potential synthetic intermediates of bioactive compounds. Depending on their substitution, tetrahydroindoles or octahydroindoles could selectively be obtained.
Diastereoselective synthesis of bicyclic amino acids via ring contraction of α-chlorolactams
作者:R. Henning、H. Urbach
DOI:10.1016/s0040-4039(00)87863-6
日期:——
Bicyclic lactams were converted to their α-chloro-derivatives and subjected to ringcontraction under basic conditions to give bicyclic acids in diastereoselective fashion.
