Induction of one-handed helix sense in achiral poly(N-propargylamides)

Achiral N-propargylamides, i.e., N-propargyl-3-methylbutanamide (1), N-propargyl-2-ethylbutanamide (2), and N-propargyl-3,3-dimethylbutanamide (3), were polymerized with (nbd)Rh+[η6-C6H5B- (C6H5)] to afford polymers with moderate molecular weights (Mn = 6000-22000) in good yields. The 1H NMR and UV-vis spectra demonstrated that the polymers, poly(1)-poly(3), have stereoregular structures (cis = 100%) and equally populated right- and left-handed helical conformation. A predominant helix sense was induced in these polymers by the addition of chiral alcohols or amine, which was confirmed by CD and UV-vis spectroscopies. 1H NMR and CD spectroscopic studies strongly suggested that the poly(N-propargylamides) interacted with the chiral alcohols by hydrogen bonding at the amide groups of the polymer side chain. Chiral terpenes could also induce single-handed helical conformation. It is likely that hydrophobic interaction led to the one-handed helical conformation in the case of the chiral terpenes because the addition of n-hexane decreased the CD signal.

Palladium-Catalyzed Migratory Insertion of Carbenes and C-C Cleavage of Cycloalkanecarboxamides

A palladium catalyzed reaction of cycloalkanecarboxamides and diazomalonates or bis(phenylsulfonyl)diazomethane has been developed. The reaction proceeds via carbene migratory insertion and cascade C-C cleavage pathways. Cycloalkanecarboxamides with four to seven membered rings are applicable in the transformation. A series of ring opening products were prepared with moderate yields. The finding provides valuable clues for the development of new reactions involving carbene migratory insertion and the cleavage of unstrained C(sp3)-C(sp3) bonds.

Enantio- and Diastereoswitchable C?H Arylation of Methylene Groups in Cycloalkanes

A complementary set of chiral N,N-ligands enables the Pd-catalyzed β-C?H arylation of unbiased internal methylene groups in good yield and with high levels of enantio- and diastereoinduction. Both the dia- and enantioselectivity can be reversed, thus allowing the selective arylation of any of the four β-C?H bonds in cycloalkanecarboxamides of various ring sizes. The method is applicable to a broad range of aryl iodides with electron-withdrawing and -donating substituents in the o-, m-, or p-position.

Synthesis of 1,3-Diketones and β-Keto Thioesters via Soft Enolization

Ketones and thioesters undergo soft enolization and acylation using crude acid chlorides on treatment with MgBr2·OEt2 and i-Pr2NEt to give 1,3-diketones and β-keto thioesters, respectively. The use of crude acid chlorides adds efficiency and cost reduction by avoiding the need to purify and/or purchase them. The process is conducted in a direct fashion that does not require prior enolate formation, further enhancing its efficiency and making it very easy to carry out. The method is suitable for large scale applications. ?

Direct C-C Bond Formation from Alkanes Using Ni-Photoredox Catalysis

A method for direct cross coupling between unactivated C(sp3)-H bonds and chloroformates has been accomplished via nickel and photoredox catalysis. A diverse range of feedstock chemicals, such as (a)cyclic alkanes and toluenes, along with late-stage intermediates, undergo intermolecular C-C bond formation to afford esters under mild conditions using only 3 equiv of the C-H partner. Site selectivity is predictable according to bond strength and polarity trends that are consistent with the intermediacy of a chlorine radical as the hydrogen atom-abstracting species.

Bidentate ligand 8-aminoquinoline-aided Pd-catalyzed diastereoselective β-arylation of the prochiral secondary sp3 C-H bonds of 2-phenylbutanamides and related aliphatic carboxamides

Investigations on the Pd-catalyzed 8-aminoquinoline-aided diastereoselective β-arylation of the prochiral 2° sp3 C-H bonds of various aliphatic carboxamides having substituents at the α- or γ-positions are reported. The Pd-catalyzed β-arylation of the 2° sp3 C-H bonds of racemic 2-phenylbutanamides with aryl iodides gave the arylated products (±)-3a-l (anti isomers) with moderate to good diastereoselectivities (dr up to 86:14). Next, the Pd-catalyzed β-arylation of various γ-substituted aliphatic carboxamides with aryl iodides furnished the corresponding C-H arylated products with poor diastereoselectivities. Then, the arylation of the C(β)-H bonds of 2-ethyl-N-(quinolin-8-yl)butanamide possessing two prochiral centers with aryl iodides successfully furnished the bis arylated products meso-8eA-hA and (±)-8eB-hB (diastereomers). The arylation of (S)-2-phenylbutanamide also gave the corresponding enantiomerically enriched compounds 10a-c (anti isomers). The stereochemistry of the products (±)-3a-l (major isomers), meso-8eA-hA (major isomers), (±)-8eB-hB (minor isomers) and enantiomerically enriched compounds 10a-c (major isomers) were assigned based on the X-ray structures of the major isomers 3b,c,e,l, 8eA, 10c and minor isomers 8eB and 8fB. The limitations and outcome of the stereocontrol in the Pd-catalyzed C-H arylation reactions involving aliphatic carboxamides are illustrated.
