Cyclopropyl methyl
WebMethyl 1-aryl-2-amino-cyclopropane carboxylates have been readily synthesized in high yields by Rh-catalyzed decomposition of aryldiazoacetates in the presence of N-vinylphthalimide. The reaction is highly trans -selective. T. Melby, R. A. Hughes, T. Hansen, Synlett, 2007 , 2277-2279. WebPreparation of the resin-bound enamide was achieved by activation of the resin-bound β-keto ester with dimethylformamide dimethyl acetal for 18 h followed by in situ addition of cyclopropylamine at room temperature for 72 h. Cyclization with TMG in DCM at 55°C for 18 h afforded the corresponding resin-bound quinolone.

WebThe major phase 1 metabolite was identified as 4-cyclopropyl-5-hydroxy-6-methyl-N-(4-hydroxy)-phenyl-2-pyrimidinamine (metabolite 2). This metabolite was excreted in the urine as β-glucuronic acid conjugate, as well as mono- and disulfuric acid conjugates. Although female rats formed the monosulfate almost exclusively, the males excreted equal ... Due to the unfavoured bond angles (60°), cyclopropyl groups are highly strained. Two orbital models were proposed to describe the bonding situation. The Coulson-Moffit model uses bent bonds. The C-C bonds are formed by overlap of two sp-hybrid orbitals. To adapt to the small bond angle, there is some rehybridization resulting in sp -hybrids for the ring bonds and sp for the C-H bonds. This model resembles the banana bond model for C=C double bonds (τ bonds).
