PHOTOCHEMISTRY OF 1,3-CYCLOPENTANEDIONES. OXETANE FORMATION INVOLVING BOTH ENERGY TRANSFER AND ELECTRON TRANSFER PROCESSES
Eriksen, Jens,Plith, Preben E.
, p. 481 - 484 (1982)
Photolysis of 2,2-dimethyl-1,3-cyclopentanedione in acetone resulted in oxetane formation in a two photon process involving energy transfer from triplet excited acetone and electron transfer from singlet excited acetone.

Synthetic cannabinoids, as exemplified by SDB-001 (1), bind to both CB1 and CB2 receptors and exert cannabimimetic effects similar to (-)-trans-Δ9-tetrahydrocannabinol, the main psychoactive component present in the cannabis plant. As CB1 receptor ligands were found to have severe adverse psychiatric effects, increased attention was turned to exploiting the potential therapeutic value of the CB2 receptor. In our efforts to discover novel and selective CB2 receptor agonists, 1 was selected as a starting point for hit molecule identification and a class of 1H-pyrazole-3-carboxamide derivatives were thus designed, synthesized, and biologically evaluated. Systematic structure-activity relationship investigations resulted in the identification of the most promising compound 66 as a selective CB2 receptor agonist with favorable pharmacokinetic profiles. Especially, 66 treatment significantly attenuated dermal inflammation and fibrosis in a bleomycin-induced mouse model of systemic sclerosis, supporting that CB2 receptor agonists might serve as potential therapeutics for treating systemic sclerosis.
Synthesis of γ-, δ-, and ε-lactams by asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters

Highly enantiomerically enriched γ- and δ-lactams have been prepared by a simple and very efficient procedure that involves the asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters followed by desulfinylation of the nitrogen atom and spo
A SIMPLE SYNTHETIC APPROACH TO Cbz-Phe-Ψ-(CH2)Gly-Pro-OMe AND RELATED PEPTIDE ISOSTERES

, p. 3579 - 3582 (2007/10/02)
A new approach to ketomethylene and hydroxymethylene peptide isosteres has been developed which is simple, direct, and highly convergent.A key feature is construction of the central bond of a γ-keto ester by alkylation of a t-butyl β-keto ester with an α-bromo ester.
Reactions of Propargyl Alcohols with Amide Acetals
Parker, Kathlyn A.,Petraitis, Joseph J.,Kosley, Raymond W.,Buchwald, Stephen L.
, p. 389 - 398 (2007/10/02)
The reaction of a propargyl alcohol with an amide acetal affords enamine products, an allenic amide (a sigmatropic rearrangement product), or a product resulting from enamine formation followed by sigmatropic rearrangement.Subsequent procedures afforded α,β-unsaturated aldehydes, α-hydroxy ketones, β-keto amides, and spiro lactones.
