rac-(3aR,6aR)-(E)-Methyl 2-(3a-methyl-perhydro-furo[3,2-b]furan-2-yl-idene)acetate.

ABSTRACT

The constitution and relative configuration at the stereogenic centres and stereochemistry of the C-C double bond formed during Pd(II)-catalysed domino reaction was established by X-ray analysis of the title compound, C(10)H(14)O(4). The asymmetric unit contains two mol-ecules.
