The Key Role of Water in the Heterogeneous Permanganate Oxidation of ω-Hydroxy Alkenes
Baskaran, Sundarababu,Islam, Imadul,Vankar, Padma S.,Chandrasekaran, Srinivasan
, p. 1670 - 1671 (1990)
Potassium permanganate-copper sulphate in dichloromethane in the presence of a catalytic amount of water effects a smooth oxidative cyclization of ω-hydroxy alkenes to ω-lactones in good yields with the net loss of one or more carbon atoms in the procees.
Improved enantioselection for chiral dirhodium(II) carboxamide-catalysed carbon-hydrogen insertion reactions of tertiary alkyl diazoacetates
Doyle,Zhou,Raab,Roos
, p. 4745 - 4748 (1995)
Enantiocontrol in C-H insertion reactions of 3° alkyl diazoacetates, which is highly dependent on the catalyst ligand, is greatly enhanced with the use of dirhodium(II) tetrakis[methyl 1-acetylimidazolidin-2-one-4(S)-carboxylate), Rh2(4S-MACIM)4.
Tandem polar/radical crossover sequences for the formation of fused and bridged bicyclic nitrogen heterocycles involving radical ionic chain reactions, and alkene radical cation intermediates, performed under reducing conditions: Scope and limitations
Crich, David,Ranganathan, Krishnakumar,Neelamkavil, Santhosh,Huang, Xianhai
, p. 7942 - 7947 (2007/10/03)
It is demonstrated that phosphorylated forms of β-nitro alcohols provide an excellent means of entry into β-(phosphatoxy)alkyl radicals on exposure to tributyltin hydride and AIBN in benzene at reflux. These radicals then undergo heterolytic cleavage of t
Generation and reaction of alkene radical cations under nonoxidizing conditions: Synthesis of the pyrrolizidine nucleus
Crich, David,Ranganathan, Krishnakumar,Huang, Xianhai
, p. 1917 - 1919 (2007/10/03)
(equation presented) Stable β-phosphatoxy nitroalkanes, readily assembled by the Henry reaction and subsequent phosphorylation, serve as good precursors to alkene radical cations on treatment with triphenyltin or tributyl hydride and AIBN in benzene at re
Stereocontrolled routes to bridged ethers by tandem cyclizations
Marson, Charles M.,Campbell, Jon,Hursthouse, Michael B.,Malik, K. M. Abdul
, p. 1122 - 1124 (2007/10/03)
Ring contraction of a 3,4-epoxyalcohol, then lactolization and electrophilic attack are the steps in the domino cyclization protocol for the formation of 8-oxabicyclo[3.2.1]octane systems.
A General Approach to the Synthesis of Butanolides: Synthesis of the Sex Pheromone of the Japanese Beetle
Baskaran, Sundarababu,Islam, Imadul,Chandrasekaran, Srinivasan
, p. 891 - 895 (2007/10/02)
A variety of substituted γ-hydroxy olefins 1 have been converted to butanolides 4 in very high yield in a three-step sequence involving bromoetherification, elimination, and oxidative cleavage.The key step in the overall transformation is the highly selective oxidative cleavage of enol ethers 3 with PCC under very mild reaction conditions.Application of this methodology has been exemplified in the synthesis of the Japanese beetle pheromone.
OXIDATION OF TETRAHYDROFURAN METHANOL DERIVATIVES WITH PYRIDINIUM CHLOROCHROMATE: A FACILE SYNTHESIS OF γ-BUTYROLACTONES
Baskaran, S.,Chandrasekaran, S.
, p. 2775 - 2778 (2007/10/02)
Treatment of a number of tetrahydrofuran methanol derivatives with pyridinium chlorochromate led to the formation of the corresponding γ-butyrolactones with the loss of one or more carbon atoms in good yields under mild reaction conditions.
