9. Iveta Luntēna

Host institution: Aalto University, Helsinki

http://chemistry.aalto.fi/en/research/koskinen_group

Aim: Acquirement of advanced asymmetric synthetic methods of analogues of natural compounds - investigation and development of short and stereoselective synthetic sequence to decahydroisoquinoline frameworks utilizing amino acids as starting materials.

Results: During the research period scalable stereocontrolled synthesis of exo-methylene cyclization precursor was developed using Barbier reaction of amino aldehyde and allylic bromide. This also involved finding the optimal methods for decagram scale synthesis of precursors.

During the screening of various cyclization conditions (base mediated, radical mediated and transition metal mediated), the desired cyclization was finally achieved using iodine and base in aqueous THF. This mechanistically complex cyclization proceeds via several intermediates and allows obtaining the challenging anti-Markovnikov addition product. Thus the short 6 step sequence allows to generate significant molecular complexity (4 stereocenters, 2 fused rings) from simple and cheap starting materials. Importantly the configuration of the two unchangeable stereocenters of the model compound matches the configuration of the D-E-F core of steroidal alkaloids from Veratrum family.

Aim: Gathering expertise in synthesis of organoselenium compounds in the research of organoselenium compounds

Results: The work done during the visit mainly was devoted to exploration of electronic effects on the demethylation and/or demethylation/intramolecular cyclization of (6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)(phenyl)methanone and (6-methoxy-2-(4-methoxyphenyl)benzo[b]selenophen-3-yl)(phenyl)methanone derivatives and their corresponding reduced forms (alcohols instead of ketones). Consequently, new type of polycyclic benzo[b]selenophene derivatives (10H-benzo[b]indeno[2,1-d]selenophene based) was obtained, which is interesting particularly due to the close geometric resemblance with the molecular scaffold of promising selenium analogues of raloxifene.

Aim: to scale up synthesis of previously designed and synthesised pyrrolidine catalyst in prof. Pihko group, design and synthesis of new indole-based pyrrolidine catalyst.

Results: Besides inherent experience on work organization, a successful scale up for a pyrrolidine catalyst that has been designed and synthesised in prof. Pihko group earlier was done, also development and synthesis of new electron poor pyrrolidine catalyst with indole-based design. Indole-based pyrrolidine catalyst has been tested in enantioselective Mukaiyama-Michael reaction. The synthesis was based on known methods although some improvements and changes in these methods were made.

As soon as desired pyrrolidine catalyst with indole function was obtained, it was tested in enantioselective Mukaiyama-Michael reaction. Unfortunately no enantioselectivity improvements were made, that means catalyst should be optimized.
