, p. 4931 - 4937 (2016/07/19)
A short and concise formal synthesis of enantiopure dihydroartemisinic acid from (R)-citronellal is described in this article. Intramolecular version of asymmetric Stetter reaction using Rovis aminoindane based NHC catalyst was explored to access the core
Cyclopropenium-activated cyclodehydration of diols
Kelly, Brendan D.,Lambert, Tristan H.
supporting information; experimental part, p. 740 - 743 (2011/05/04)
The dehydrative cyclization of diols to cyclic ethers via cyclopropenium activation is described. Using 2,3-diphenylcyclopropene and methanesulfonic anhydride, a series of 1,4-and 1,5-diols are rapidly cyclized to furnish tetrahydrofurans and tetrahydropyrans in high yield. Eleven total substrates are shown, including a gram scale cyclization of a diterpene derivative.
Enantioselective synthesis of three stereoisomers of 5,9- dimethylpentadecane, sex pheromone component of Leucoptera coffeella, from (-)-isopulegol
Moreira, Jardel A.,Correa, Arlene G.
, p. 3787 - 3795 (2007/10/03)
The coffee leaf miner, Leucoptera coffeella, is an economically important pest of coffee trees in Brazil. It has been demonstrated that the main sex pheromone component of this species is 5,9-dimethylpentadecane, however the stereochemistry of the natural
