A method for the selective hydrolysis of ketone hydrazones in the presence of acetals
Ulven,Carlsen
, p. 3971 - 3972 (2000)
Dimethylhydrazones and RAMP-hydrazones containing acetal or olefin groups were hydrolysed selectively to form the corresponding ketones, by treatment with ammonium dihydrogen phosphate buffer solutions.

The first synthesis of luffarin L (1) and 16-epi-luffarin L (2) by a silicon-tethered ring closing metathesis as a key step has been achieved. The stereochemistry and absolute configuration of the natural sesterterpenolide luffarin L (1) and a new route f
Synthesis of all diastereomers of the 2-deoxypentoses and the 2,6-dideoxyhexoses from 2-phenyl-1,3-dioxan-5-one hydrate
Ulven, Trond,Carlsen, Per H. J.

All diastereomers of the 2-deoxypentoses and the 2,6-dideoxyhexoses were synthesized from 2-phenyl-1,3-dioxan-5-one hydrate (1), by alkylation via the RAMP-hydrazone (2). Some of the diastereomers were synthesized in the racemic form via the dimethylhydrazone (28). The 2-deoxypentoses were synthesized by alkylation with allyl bromide, followed by stereoselective reduction, ozonolysis, and deprotection. The 2,6-dideoxypentoses were synthesized by dialkylation with allyl bromide and methyl iodide.
