We have employed Bi(OTf)3 (5 mol %) a catalyst not previously used in the synthesis of urea condensation products from α-dicarbonyl compounds, as a mild method for the synthesis of difficult to obtain glycolurils. There are limited synthetic examples of C-alkylated substituted glycolurils and even fewer carrying functionality on the alkyl substituent. We have successfully synthesised some challenging examples of glycolurils with functionality, which include norbornyl-based structures. The milder reaction conditions enables the isolation of defined intermediate diols and ureas in good yields, and glycolurils are possible, where they would not normally be available under conventional acid catalyzed conditions.
Enzymatic Baeyer-Villiger oxidations of some bicycloheptan-2-ones using monooxygenases from Pseudomonas putida NCIMB 10007: enantioselective preparation of a precursor of azadirachtin

Two monooxygenases MO1 (NADH dependent) and MO2 (NADPH dependent) isolated from Ps. putida NCIMB 10007 have been utilized as biocatalysts in Baeyer-Villiger oxidations.The former enzyme oxidized the racemic ketones 9, 10 and 14 into
