We conducted a structure-activity relationship study to explore simplified analogues of the itraconazole (ITZ) scaffold for their ability to inhibit the hedgehog (Hh) signaling pathway. These analogues were based on exploring the effects of chemical modifications to the linker and triazolone/side chain region of ITZ. Analogue 11 was identified as the most potent compound in our first generation, with an IC50 value of 81 nM in a murine Hh-dependent basal cell carcinoma. Metabolic identification studies led us to identify truncated piperazine (26) as the major metabolite in human liver microsomes (HLMs) and an improved Hh pathway inhibitor (IC50 = 22 nM). This work verifies that continued truncation of the ITZ scaffold is a practical method to maintain potent anti-Hh activity while also reducing the molecular weight for the ITZ scaffold and achieving improved pharmacokinetic properties.

A catalyst-free and solvent-free method for the hydroboration of a variety of carboxylic acids with pinacolborane was developed. The hydroboration of various aromatic and aliphatic carboxylic acids as well as dicarboxylic acids with HBpin could be completed within 6 h at room temperature or within 1 h at 60 degrees C to give the products in quantitative yields under neat conditions without the need for any solvent or metal catalyst. The possible reaction mechanism was investigated in detail based on the corresponding DFT calculations and the stoichiometric reaction of acetic acid with different equivalents of HBpin (at room temperature and 0 degrees C) and it revealed the stepwise nature of the protocol.

Rh(I)-Catalyzed [3+ 2] annulation reactions of cyclopropenones with amides are reported. The reaction provides a direct approach for producing highly substituted alpha, beta-unsaturated gamma-lactam derivatives. The presence of an N(sp(2)) atom in the N-alkyl group of the amide, such as the 2-pyridinylmethyl or 8-aminoquinonyl group, is essential for the success of the reaction.

The first asymmetric Pd-II-catalyzed aminofluorination of unactivated alkenes using chiral quinoline-oxazolines (Quox) as ligands has been developed. This reaction provides easy access to a wide array of enantiomerically enriched beta-fluoropiperidines in good yields and with excellent enantioselectivity. Notably, Et4NF.3 HF as a readily accessible nucleophilic fluoride source was found to play an essential role in the enantioselective control, and CsOCF3 also acts a key additive to improve the excellent ee value of products.

New chiral regioisomeric gamma-hydroxyphosphine ligands were synthesized from alpha-pinene. The key transformation was the thermal [2,3]-sigmatropic rearrangement of allyldiphenylphosphinites, obtained from (1R,2R,4S,5R)-3-methyleneneoisoverbanol and (1R,2R,3R,5R)-4-methyleneneoisopinocampheol, to allylphosphine oxides. Hydroxy groups were introduced stereoselectively through a hydroboration-oxidation reaction proceeding from the less hindered site providing a trans relationship between the hydroxy and the phosphine substituents.

We report the desiging of ultrafine Pd-based nanocatalyst containing N-doped carbon structure (Pd@NC). The material was prepared by direct dehydration at 120 degrees C followed by mixing and heating with a dopant (ammonium oxalate) at 150 degrees C in a furnace. The Pd@NC nanocatalyst containing electron-rich pyridinic-N doped carbon structure, was thoroughly characterized by various techniques namely SEM, EDX, TEM, FTIR, ICP-AES, XRD, XPS, TGA and Raman spectroscopy. The utility of the Pd@NC nanocatalyst was explored for base-free Knoevenagel condensation and 4H-pyran derivatives and also in the reduction of nitroarenes under mild and greener conditions. Further, the optical property was explored using photoluminescence spectroscopy and band gap was also calculated. The heterogeneous nature and stability of the catalyst facilitated by its ease of separation for long-term performance and recycling studies showed that catalyst was robust and remained active upto six recycling experiments. Also, the leaching of metal was confirmed by ICP-AES. The superiority of the catalyst was attributed to the metal support interaction (MSI) between metallic palladium and pyridinic-N doped carbon to acquire excellent catalytic activity and changing the reducing nature of NaBH4 towards nitro functionality. The MSI between pyridinic-N dopant on the carbon structure and PdNPs produces highly active sites for catalytic performance under mild conditions.

Enantioselective formation of cyclohexene derivatives bearing an all-carbon quaternary stereogenic center is described. The racemic cyclohexenes are readily transformed to chiral substituted cyclohexenes in good yield with excellent enantioselectivity and diastereoselectivity by a palladium-mediated deracemization. The resulting products are promising synthetic intermediates of biologically active natural products. This protocol provides us with a new entry to the concise and scalable synthesis of multifunctionalized compounds.

Through a screen of over one hundred and 30 permutations of reaction temperatures, solvents, carbodiimide resins, and carbodiimide molar equivalences, in the presence, absence, or combination of diisopropylamine and benzotriazole additives, a convenient and first reported carbodiimide polymer-assisted flow approach to effect amide coupling and lactamization was developed. The protocol entails injecting a single solution (1:9 dimethylformamide: dichloromethane) containing a carboxylic acid and an amine or linear peptide sequence into a continuous stream of dichloromethane. The protocol remained viable in the absence of base, did not require carboxylate preactivation which, and in concert with minimal workup requirements, enabled the isolation of products in high yields. Compared to the utilization of untethered carbodiimide reagents, the flow procedure was also observed to provide a degree of racemization safety.
