Concise synthesis of (+)-β-benzyl γ-butyrolactones from butynediol
Kamlage,Sefkow,Zimmermann,Peter
, p. 77 - 80 (2002)
The synthesis of optically active β-benzyl-γ-butyrolactones from butynediol via four transition metal catalysed reactions is reported. Key reactions are the hitherto unknown enantioselective hydrogenation of 2-benzyl-2-buten-1,4-diols using Ir(I) phosphinooxazoline catalysts and the regiocontrolled oxidation of the resulting 2-benzyl-1,4-butanediols to the β-substituted butyrolactones.

Synthesis of an optically active γ-lactone related to tricarballylic acid (TCA) and correlation of this to the same lactone derived from the two sidechain TCA esters at C-14 and C-15 of fumonisin B1 has established that these esters have the R configuration.
