The metabolic options open to lactones fused to alicyclic rings (Nos 1161–1166) include excretion as the open-chain hydroxycarboxylic acid derivative, hydroxylation of ring alkyl substituents producing polar metabolites that may be excreted (Madyastha & Raj, 1993), or oxidative degradation of the carboxylic acid side-chain to yield polar alicyclic or aromatic carboxylic acids that are excreted unchanged or in conjugated form (Brewster et al., 1977a).
Metabolic pathways available to aromatic fused-ring lactones (Nos 1167–1172) include excretion as the glycine or glutamine conjugates of the open-chain hydroxycarboxylic acid derivative, or oxidation or reduction of the side-chain and subsequent excretion as the glucuronic acid conjugate (Ambrose et al., 1933; James et al., 1972).

AB - A short approach for the synthesis of 3,4-fused γ-lactone-γ-lactam bicyclic systems (1) in diastereomeric mixtures from chiral D-alanine methyl ester hydrochloride is described. The key step towards lactonisation is the reduction of the carbonyl ketone of the 5R-configured 3,5-dimethylpyrrolidine-2,4-dione diastereomers (8) via sodium borohydride in the presence of hydrochloric acid. With the presence of ethyl acetyl functionality at C3-position, ester hydrolysis of 8 occurred concomitantly with keto reduction leading to lactonisation and eventually affording the anticipated (3S,4S,5R), (3R,4R,5R), (3R,4S,5R) and (3S,4R,5R) bicyclic moieties. The formation of the fused systems was confirmed by mass spectroscopy (MS) and nuclear magnetic resonance (NMR) analyses.
