Pozycja Profesor Ryszard Bodalski – wspomnienia(Wydział Chemiczny, Politechnika Łódzka, 2019) Janecki, Tomasz; Albrecht, ŁukaszPozycja Profesor Henryk Krawczyk – wspomnienia(Wydział Chemiczny, Politechnika Łódzka, 2018) Albrecht, ŁukaszPozycja Organocatalytic Enantioselective Approach to Spirocyclic Δβ,γ-Butenolides(2014) Hejmanowska, Joanna; Dzięgielewski, Marek; Kowalczyk, Dorota; Albrecht, ŁukaszA novel method for the preparation of the spirocyclic Δβ,γ-butenolides is presented. The developed strategy is based on a trienamine-mediated [4+2]-cycloaddition between (E)-3-alkylidene- 5-arylfuran-2(3H)-ones and 2,4-dienals. Target products containing three contiguous centres including one quaternary are efficiently formed in a highly enantiomerically enriched form in the presence of the silyl-protected diphenylprolinol aminocatalyst.Pozycja A Convenient Approach to a Novel Group of Quaternary Amino Acids Containing a Geminal Bisphosphonate Moiety(2014) Dzięgielewski, Marek; Hejmanowska, Joanna; Albrecht, ŁukaszQuaternary amino acids containing a geminal bisphosphonate moiety have been synthesized for the first time. The developed two-step reaction sequence utilizes the Michael addition of α-substituted azlactones to a vinylidene bisphosphonate as the key step. The reaction proceeds under catalytic conditions with excellent regioselectivity. Subsequent, acid-mediated azlactone ring opening affords the target quaternary amino acids with good overall yields. Attempts to develop an enantioselective version of the synthetic strategy are described.
