    • The absolute configuration of (+)-1a is thought to be S as illustrated. This is based on correlations carried out with the corresponding (+)-1b. Briefly. Diels - Alder cycloaddition with cyclopentadiene proceeds in the expected endo fashion and on the face of the alkene opposite the acyloxy group. Transacetalization of this cycloadduct either with methanol or with water leads to two adducts identical to those obtained from the cycloaddition followed by analogous transacetalization of (5R)-3 except that the optical rotations are opposite. The configuration of (+)-1b is therefore S and (+)-1a also S by analogy.

    • The lipase does not catalyze ring-opening of the lactone at a detectable rate.

    • The absolute configuration is indicated as analogous to 1; this remains to be proven.
