• Algal transformations of three cyclic β-keto esters, methyl 2-oxocyclopentanecarboxylate (MCPC), ethyl 2-oxocyclohexanecarboxylate (ECHxC), and methyl 2-oxocycloheptanecarboxylate (MCHpC) were photo-autotrophically studied with an axenic strain of Chlorella pyrenoidosa Chick. The three cyclic β-keto esters were transformed in two manners; reduction of the carbonyl group to a hydroxy group and elimination of the alkoxycarbonyl group. The former reaction occurred more often than the latter. The cis/trans ratios of the resulting alcohols in MCPC, ECHxC and MCHpC were 13 : 87,15 : 85,and 65 : 35,respectively. The alkoxycarbonyl group elimination products were as follows : cyclopentanone and cyclopentanol in MCPC, cyclohexanone and cyclohexanol in ECHxC, and cycloheptanone in MCHpC.
