日期:——
The thermolyses of 3-(3-methyldiazirin-3-yl)propan-1-ol (1) and 3-(3-methyldiazirin-3-yl)propanoic acid (2) have been studied in solution over the temperature range 96–125 °C. The reactions are unimolecular and fit linear Arrhenius plots with K(1)= 1013.85 ± 0.69exp[–31.80 ± 1.21 kcal mol–1/RT]s–1 and K(2)= 1012.38 ± 0.43exp[–29.26 ± 0.75 kcal mol–1/RT]s–1

compositions of the alcohol mixtures formed in nitrousaciddeaminations of cyclopropylmethylcarbinylamine, (2-methylcyclopropyl)-carbinylamine, 2-methylcyclobutylamine, 3-methylcyclobutylamine, crotylcarbinylamine and allylmethylcarbinylamine have been determined. These results and the behavior of the corresponding alcohols under isomerization conditions in strongly acidic media may be explained by assuming formation
Absolute Configuration and Total Synthesis of (+)-Curacin A, an Antiproliferative Agent from the Cyanobacterium <i>Lyngbya majuscula</i>

日期:1997.1.1
The absoluteconfiguration of curacin A was determined as (2R,13R,19R,21S)-1 by comparison of degradation products 2 and 3 with the same materials prepared by asymmetricsynthesis. The total synthesis of 1 was completed from (1R,2S)-2-methylcyclopropanecarboxylic acid (8) and the amino alcohol derivative 46. The latter was prepared from 4-pentynal (14) and the Garner aldehyde (43). Asymmetric allylation
Surprising Reactivity in NiXantphos/Palladium-Catalyzed α-Arylation of Substituted Cyclopropyl Nitriles
作者:Brandon A. Wright、Michael J. Ardolino
DOI:10.1021/acs.joc.8b02238
日期:2019.4.19
α-Arylations of cyclopropyl and related nitriles provide access to important synthetic intermediates and pharmacophores for biologically active molecules. However, robust methods for coupling of sterically encumbered partners have remained elusive. Through optimization using high-throughput experimentation (HTE), the NiXantphos ligand was found to be effective in the coupling of sterically hindered
