A convenient method for lactonization of α-allyl esters using iodine in dimethylsulphoxide
Nawghare, Beena R.,Gaikwad, Sunil V.,Pawar, Bharati V.,Lokhande, Pradeep D.
, p. 469 - 473 (2014/12/11)
A simple method for the synthesis of α-γ-disubstituted-γ-butyrolactones by cyclization of α-allyl esters using iodine in dimethylsulphoxide is reported. This method is efficient and operationally simple in comparison to methods using transition metal comp
Tellurium in organic synthesis: A new approach to trisubstituted γ-butyrolactones with trans-trans relative stereochemistry. Total enantioselective synthesis of (-)-Blastmycinolactol, (+)-Blastmycinone, (-)-NFX-2, and (+)-Antimycinone

scheme or table, p. 6843 - 6846 (2011/03/18)
The total synthesis of (-)-Blastmycinolactol, (+)-Blastmycinone, (-)-NFX-2, and (+)-Antimycinone was accomplished in few steps in high yields and ee, starting from enantiomerically enriched (S)-Z-vinylic hydroxytellurides.
Tellurium in organic synthesis: synthesis of bioactive butenolides
Bassora, Bruno K.,Da Costa, Carlos E.,Gariani, Rogério A.,Comasseto, Jo?o V.,Dos Santos, Alcindo A.
, p. 1485 - 1487 (2008/02/02)
Reduction of (Z)-β-butyltelluro-enones gives the corresponding γ-hydroxy vinylic tellurides with retention of the double bond configuration. Reaction of γ-hydroxy vinylic tellurides with 2 equiv of n-butyllithium produces 1,4-C,O-dianions, which on reaction with carbon dioxide give the corresponding butenolides.
Convenient synthesis of volatile Streptomyces lactones
Amonkar, Chandan P.,Tilve, Santosh G.,Parameswaran
, p. 2341 - 2344 (2007/10/03)
A convenient three-step synthetic approach towards 3-alkyl-5-methyl-2[5H] furanones is described. The steps involved in the synthesis are domino primary alcohol oxidation-Wittig reaction, acid-catalysed lactonisation and isomerisation. This synthetic appr
A total synthesis of (-)-antimycin A(3b)

, p. 7667 - 7671 (2007/10/03)
(-)-Antimycin A(3b), the antipode of natural antibiotic antimycin A(3b), was synthesized utilizing the asymmetric aza-Claisen rearrangement. (C) 2000 Elsevier Science Ltd.
A New Synthesis Of Streptomyces Lactones By 1,3-Dipolar Cycloaddition
Chiacchio, Ugo,Bella, Maria R. Di,Rescifina, Antonio,Romeo, Giovanni,Uccella, Nicola
, p. 2209 - 2214 (2007/10/02)
The cycloaddition of nitrones (4) to propene, followed by sequential treatment with methyl trifluoromethanesulfonate, H2-Pd/C, and m-chloroperbenzoic acid, is shown to provide a general method for the preparation of a variety of volatile streptomyces lactones.
THE SYNTHESIS OF VOLATILE STREPTOMYCES LACTONES
Kan-Yin, Zhang,Borgerding, Anthony J.,Carlson, Robert M.
, p. 5703 - 5706 (2007/10/02)
A synthetic pathway to the volatile streptomyces lactones has been developed using as a key step sequential addition / alkylation to anions generated from 2,2-dimethyl-5-methylene-1,3-dioxane.
