- The deprotection of the chiral N-sulfonyl aziridines 1-3 has been studied under different desulfonylation conditions. Two methods for the efficient deprotection of 2-benzyl-, 2-phenyl-, and 2-carboxyl-N-sulfonylaziridines were found. The desulfonylation

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The mechanism of the palladium-catalyzed elimination of acetic acid from allylic acetates has been studied. It was found that this process can take place not only via conventional syn elimination of palladium hydride but also via an anti elimination. pat

- A set of new chiral bis-oxazolines, 5a-b and 6a-c, has been synthesised from D and L-diethyl 2,3-O-isopropylidene tartrates and chiral amino alcohols. These ligands were found to be efficient in the Cu(I)-catalysed asymmetric cyclopropanation of olefins.
