Rhodium-catalyzed asymmetric 1,4-addition of organoboron reagents to 5,6-dihydro-2(1H)-pyridinones. Asymmetric synthesis of 4-aryl-2-piperidinones.

T Senda et al.

The Journal of organic chemistry, 66(21), 6852-6856 (2001-10-13)

Catalytic asymmetric synthesis of 4-aryl-2-piperidinones was realized for the first time by asymmetric 1,4-addition of arylboron reagents to 5,6-dihydro-2(1H)-pyridinones in the presence of a chiral bisphosphine-rhodium catalyst. In the reaction introducing 4-fluorophenyl group, the use of 4-fluorophenylboroxine and 1 equiv

Synthesis and anticonvulsant activities of 3,3-dialkyl- and 3-alkyl-3-benzyl-2-piperidinones (delta-valerolactams) and hexahydro-2H-azepin-2-ones (epsilon-caprolactams).

P A Reddy et al.

Journal of medicinal chemistry, 40(1), 44-49 (1997-01-03)

A series of 3-substituted 2-piperidinone (delta-valerolactam) and hexahydro-2H-azepin-2-one (epsilon-caprolactam) derivatives were prepared and evaluated as anticonvulsants in mice. In the 2-piperidinone series, 3,3-diethyl compound 7b is the most effective anticonvulsant against pentylenetetrazole-induced seizures (ED50, 37 mg/kg; PI (TD50/ED50), 4.46), and

Application of an Acyl-CoA Ligase from Streptomyces aizunensis for Lactam Biosynthesis.

Jingwei Zhang et al.

ACS synthetic biology, 6(5), 884-890 (2017-04-18)

ε-Caprolactam and δ-valerolactam are important commodity chemicals used in the manufacture of nylons, with millions of tons produced annually. Biological production of these highly valued chemicals has been limited due to a lack of enzymes that cyclize ω-amino fatty acid
