Evdokimov, Nikolai M. published the artcileOne-Step Synthesis of Heterocyclic Privileged Medicinal Scaffolds by a Multicomponent Reaction of Malononitrile with Aldehydes and Thiols, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is heterocyclic privileged medicinal scaffold preparation; multicomponent reaction malononitrile aldehyde thiol; pyridine dihydropyridine chromenopyridine dithiepine preparation.

Heterocyclic privileged medicinal scaffolds involving pyridine, 1,4-dihydropyridine, chromeno[2,3-b]pyridine, and dihydro-1,4-dithiepine frameworks are prepared via a single-step multicomponent reaction of structurally diverse aldehydes with various thiols and malononitrile. Mechanistic studies of the synthetic pathway leading to pyridines reveal that 1,4-dihydropyridines undergo oxidation by the intermediate Knoevenagel adducts rather than by air oxygen. The use of o,o’-disubstituted aromatic aldehydes leads to the corresponding 1,4-dihydropyridines, whereas salicylic aldehydes result in chromeno[2,3-b]pyridines. Reactions of ethanedithiol as a thiol component produce dimeric pyridines with sterically unencumbered aldehydes, while o,o’-disubstituted aromatic aldehydes give dihydro-1,4-dithiepines. Thus, depending on the aldehyde and thiol types, diverse libraries of medicinally relevant compounds can be prepared by a simple one-step process involving no chromatog.

Maazaoui, Radhouan published the artcileDomino Methylenation/Hydrogenation of Aldehydes and Ketones by Combining Matsubara’s Reagent and Wilkinson’s Catalyst, Safety of 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is domino methylenation hydrogenation aldehyde ketone Matsubara reagent Wilkinson catalyst.

The methylenation/hydrogenation cascade reaction of aldehydes or ketones through a domino process involving two ensuing steps in a single pot is realized. The compatibility of Matsubara’s reagent and Wilkinson’s complex give a combination that allows, under dihydrogen, the transformation of a carbonyl function into a Me group. This new method is suitable to introduce an Et motif from aromatic and aliphatic aldehydes with total chemoselectivity and total retention of α-stereochem. purity. The developed procedure is also extended to the introduction of Me groups from ketones.

Hu, Zhiye published the artcileNovel class of 7-Oxabicyclo[2.2.1]heptene sulfonamides with long alkyl chains displaying improved estrogen receptor α degradation activity, Category: isoquinoline, the main research area is estrogen receptor breast cancer selective downregulators SAR; Breast cancer; Estrogen receptor; Long alkyl chains; Selective estrogen receptor downregulators; Structure-activity relationships.

Hormone therapy is widely used in clinic for breast cancer treatment, such as tamoxifen, but long-term use can cause drug resistance. In this regard, a strategy based on small mol.-induced protein degradation, i.e. selective estrogen receptor downregulator (SERD), might be an effective alternative to hormone therapy for breast cancer. However, most of the SERD candidates involve very limited scaffolds and are still in clin. trials, and none of them has been approved for marketing. In this study, a series of novel 7-oxabicyclo[2.2.1]heptene sulfonamide (OBHSA) derivatives with long alkyl chains were identified as novel SERDs. We found that the position and the length of alkyl side chain have significant effect on the biol. activity of the SERD compounds and with the six-carbon side chain was the best. Among them, compounds 23a and 36 displayed potent inhibitory activity against MCF-7 breast cancer cell line with IC50 values of 0.84μM and 0.77μM, resp., as well as excellent ERα degradation activity. Primary mechanism study indicated that the degradation of ERα is mediated through proteasome-mediated process. Flow cytometry anal. of apoptosis of 36 suggested that the effect of this type compounds on MCF-7 cells is associated with apoptosis. As such, these compounds have shown potential to become promising leads for the development of highly efficient SERDs for drug-resistance breast cancer therapies.

Addnl. data considered in abstracting and indexing are available from a source cited in the original document. A variety of substituted bromo- and iodobenzenes reacted with CH2:CMeCH2OH, CH2:CHCHMeOH, and CH2:CHCMe2OH in the presence of PdCl2 or Pd(OAc)2 and PPh3 to give, resp., Ph substituted derivatives of PhCH2 CHMeCHO, Ph(CH2)2COMe, and PhCH:CHCMe2OH. With some nonallylic unsaturated alcs., carbonyl compounds were formed via double bond migration. Formation of the intermediate aryl-substituted unsaturated alcs. was minimal unless a quaternary carbon separated the double bond from the alc. function.
