A highly diastereo- and enantio-selective intramolecular ene reaction was developed by employing a chiral titanium reagent generated in situ from TiCl2(OPri)2 and a tartrate-derived chiral 1,4-diol.This reaction afforded masked cyclohexanone and cyclopentanone derivatives with high optical purities which were synthetically useful chiral building blocks.From the intramolecular ene product (-)-epsilon-cadinene was synthesized by the use of the newly developed intramolecular Michael reaction.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 497-25-6Synthetic Route of 497-25-6

Traditional antitumor nanomedicines have been suffering from the poor tumor targeting (ca. 1%) by the enhanced permeability and retention (EPR) effect, and the low drug loading (<5%). It was postulated that engineering all-active nanoplatform could increase the therapeutic efficacy to enable the nanocarrier function as both vehicle and active ingredient. To achieve this, a photosensitizer, Ce6 was encapsulated within polymeric micelles with unsaturated fatty acids as the building blocks. Upon light irradiation, the singlet oxygen produced by Ce6 induced lipid peroxidation, resulting in the generation of both active free radicals and aldehydes. These supplementary radicals could exert cytotoxic effect for direct killing tumor cells. The aldehyde end-products induced significant cell cycle arrest at G2 phase in 4T1 cells. The peroxidation process also facilitated the on-demand disassembly of micelles and rapid release of Ce6 to maximize the therapeutic effect of singlet oxygen. These all-active micelles showed a significantly enhanced cytotoxicity with the half maximal inhibitory concentration (IC50) of 0.6 ± 0.2 mug/mL in contrast to the control micelles at 3.4 ± 0.5 mug/mL. The improved antitumor efficacy of the all-active micelles was also demonstrated in the 4T1 tumor-bearing mice in vivo. The current work provides a facile approach to enhance the antitumor efficacy of PDT nanomedicine using the biocompatible fatty acids, which can be applied to various antitumor drugs and unsaturated lipids.

Novel planar-chiral pyridinium ylides were designed, and generated in situ from the corresponding pyridinium salts with triethylamine. Ylides with a common parapyridinophane skeleton reacted efficiently with electron-deficient dicyanoalkenes, or malononitriles, to produce optically active cyclopropane derivatives with high enantioselectivity (up to 99% ee). Remote steric effects were observed on the enantioselectivities, where the R2 groups of the pyridinophane core resulted in higher ee values of the products. Density function theory (DFT) calculations are in good agreement with our experimental results: the energetically favored transition state leads to the major stereoisomer, namely the trans-cyclopropane products.

Subtype-selective agonists of the neurotensin receptor NTS2 represent a promising option for the treatment of neuropathic pain, as NTS2 is involved in the mediation of mu-opioid-independent anti-nociceptive effects. Based on the crystal structure of the subtype NTS1 and previous structure-activity relationships (SARs) indicating a potential role for the sub-pocket around Tyr11 of NT(8-13) in subtype-specific ligand recognition, we have developed new NTS2-selective ligands. Starting from NT(8-13), we replaced the tyrosine unit by beta2-amino acids (type 1), by heterocyclic tyrosine bioisosteres (type 2) and peptoid analogues (type 3). We were able to evolve an asymmetric synthesis of a 5-substituted azaindolylalanine and its application as a bioisostere of tyrosine capable of enhancing NTS2 selectivity. The S-configured test compound 2a, [(S)-3-(pyrazolo[1,5-a]pyridine-5-yl)-propionyl11]NT(8-13), exhibits substantial NTS2 affinity (4.8 nm) and has a nearly 30-fold NTS2 selectivity over NTS1. The (R)-epimer 2b showed lower NTS2 affinity but more than 600-fold selectivity over NTS1. Tyrosine surrogates: Peptides 2a,b showed that the 5-substituted azaindolylalanine is an appropriate bioisostere of tyrosine capable of enhancing NTS2 selectivity. Compound 2a exhibits single-digit nanomolar affinity (4.8 nm) and a nearly 30-fold NTS2 selectivity over NTS1.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 184346-45-0 is helpful to your research. Related Products of 184346-45-0

A highly stereocontrolled synthesis of (2S,3R,5R,6S)-6-[(1E,3R)-1,3- dimethylhex-1-enyl]-2-ethyl-2-hydroxy-3,5-dimethyltetrahydro-4H-pyran-4-one has been achieved in 13 steps and an overall yield of 7.6% from (A)-(+)-4- benzyloxazolidin-2-one. This substrate-controlled asymmetric synthesis utilized Paterson’s lactate-derived chiral ketone (2S)-2-(benzoyloxy) pentan-3-one to generate the 5R and 6S stereocentres and alkylation of an Evans’ auxiliary to generate the remote side-chain 3R stereocentre. Furthermore, a novel, highly efficient, and selective strategy was used to generate an enol trimethylsilyl ether whose subsequent Mukaiyama aldol condensation gave the acyclic precursor to the final product. A thermodynamically controlled cyclization then gave (2S,3R,5R,6S)-6-[(1E,3R)-1,3-dimethylhex-1-enyl]-2-ethyl-2-hydroxy-3, 5-dimethyltetrahydro-4H-pyran-4-one with control of the 2S and 3R stereocentres. The NMR spectroscopic data and optical rotation obtained for synthetic (2S,3R,5R,6S)-6-[(1E,3R)-1,3-dimethylhex-1-enyl]-2-ethyl-2-hydroxy-3, 5-dimethyltetrahydro-4H-pyran-4-one were consistent with those reported forthe hemiacetal isolated from Siphonaria australis, and thus, prove the absolute and relative configuration of the natural product.
