The syntheses of unsymmetrical 1,4-bifunctional allylboron reagents via Cu-catalyzed highly regio- and stereoselective 1,4-protoboration of dienylboronates were developed. The resulting allylboronates underwent chemoselective allylboration with aldehydes followed by oxidative workup to give diol products with high diastereoselectivity. Transition state analysis revealed that the disfavored transition states suffer from either a severe A1,3 allylic strain or 1,3-syn-pentane interactions. Minimization of such nonbonding 1,3-syn-pentane interactions is proposed to be the origin of observed chemoselectivity of the reaction.

A series of unprotected spirocyclic beta-prolines and beta-homoprolines are prepared by Rh-catalyzed C-H insertion. The key intermediate, a Rh nitrenoid, is generated by the N-O bond cleavage of a substituted isoxazolidin-5-one. The reaction proceeds on a gram scale with a catalyst loading of as little as 0.1 mol %, affording spirocyclic beta-amino acids that are otherwise difficult to obtain. The building blocks prepared in this work will likely find applications in medicinal chemistry.

The history of peptide chemistry in our group is described. It all started with the cyclic undecapeptide cyclosporin, the immunosuppressive compound, which is commercialised as Sandimmune/Neoral by Sandoz/Novartis, and which has revolutionized transplant medicine. The discovery that cyclosporin can be deprotonated to a hexalithio derivative, and thus C-alkylated on a sarcosine moiety, led us into a research project on peptide modifications. We defined structural prerequisites for the use of peptide enolates and for electrolytic decarboxylation of peptides. Parallel to these activities, the group was engaged in developing synthetic methodologies aimed at stereoselective preparations of alpha-, beta-, and gamma-amino acid derivatives (cf. diastereoselective alkylations, self regeneration of stereogenic centers, axially chiral enolates). A third avenue into peptide chemistry originated from our investigations on the biopolymer PHB (poly-3-hydroxybutanoic acid); the question arose ‘what happens upon replacement of chain-bound O by NH in the polyester?’ A brief summary is given of the results obtained in our ensuing discovery tour of beta-peptides built of homologated proteinogenic amino acids. They form secondary structures with short chain lengths and they have unexpected physiological properties, rendering them candidates for peptidic drugs. The synthesis of beta3-peptides is straightforward, and in the meantime most of the Fmoc-protected building blocks are commercial. The beta2-homoamino acids are less readily available. Their preparation and the assembly of a beta2- eicosapeptide with the twenty proteinogenic side chains are discussed herein. The reasons for the chosen sequence and the strategy of what turned out to be a 159-step synthesis are described. Full experimental details are given for the preparation of the dimeric Fmoc-beta2hXaa(PG)- beta2hXaa(PG)-OH building blocks used, for their solid-phase coupling to two beta2-decapeptide segments, for the thioligation, and for the purification, isolation and spectroscopic characterization of the resulting 20mer. An outlook to future projects in the exciting field of beta- and gamma-peptide chemistry and biology is given.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

An one-pot reaction of carboxylic acids and ynol ethers for the synthesis of beta-keto esters has been developed. Under promotion of Ag2O, various carboxylic acids and ynol ethers could transform to alpha-acyloxy enol esters, which undergo a following DMAP-catalyzed rearrangement to deliver beta-keto esters rapidly. This method provides a direct approach to beta-keto esters from carboxylic acids without any preactivation. The protocol features mild reaction conditions, broad substrate scope, and the products could be transformed to an array of compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 147636-36-0, you can also check out more blogs about147636-36-0

The recognition that aberrant angiogenesis contributes to the pathology of inflammatory diseases, cancer, and myocardial ischemia has generated considerable interest in the molecular mechanisms that regulate blood vessel growth. The receptor tyrosine kinase Tie-2 is expressed primarily by vascular endothelial cells and is critical for embryonic vasculogenesis. Interference with the Tie-2 pathway by diverse blocking agents such as soluble Tie-2 receptors, anti-Tie-2 intrabodies, anti-Ang-2 antibodies, and peptide-F c conjugates has been shown to suppress tumor growth in xenograft studies. An alternative strategy for interfering with the Tie-2 signaling pathway involves direct inhibition of the kinase functions of the Tie-2 receptor. Herein we describe the development of alkynylpyrimidine amide derivatives as potent, selective, and orally available ATP-competitive inhibitors of Tie-2 autophosphorylation.
