Synthesis of new mono and bis amides projected as potential histone deacetylase (HDAC) inhibitors
摘要:
In our ongoing efforts to discover new potent histone deacetylase (HDAC) inhibitors as promising anticancer candidates, we designed and synthesized a small collection of 3-substituted amines possessing macro heterocyclic skeletons bearing variable-length tails. As a metal binder domain, all the compounds possess an amide function suitable for Zn2+ chelation in the enzyme active site. A combination of solution and solid phase techniques were employed to synthesize the compounds and, as the key synthetic step to obtain the rings, a ring closing metathesis (RCM) reaction was adopted. The putative affinity of the compounds for the histone deacetylase-like protein (HDLP) model receptor active site was explored through docking calculations, and we also report preliminary studies on their pharmacological proper-ties.

The application of asymmetric phase‐transfer catalysis to the Strecker reaction of ketimines was realized utilizing bifunctional thiourea‐phosphonium salts. The asymmetric Strecker reaction of aldimines was also realized utilizing quaternaryammoniumsaltsderivedfrom amino acids.
New chiral bifunctional thiourea-phosphonium salts have been developed based on natural amino acids as highly efficient phase-transfer catalysts in the enantioselectiveaza-Henryreaction.

The enantioselective intramolecular Morita–Baylis–Hillman reaction catalyzed by amino acid-derived phosphinothiourea
A series of chiral bifunctional phosphinothioureas derived from l-amino acids have been developed to promote the enantioselectiveintramolecularMorita–Baylis–Hillmanreaction. The process afforded the cyclic hydroxyl enones with up to 84% ee and good yields under mild conditions.
