Enantioselective direct aldol reactions promoted by phosphine oxide aziridinyl phosphonate organocatalysts Doğan, Özdemir (2015-12-15) A series of phosphine oxide based chiral Lewis bases were screened as organocatalysts for silicon tetrachloride mediated direct asymmetric aldol reactions between cyclohexanone and various aromatic aldehydes. One of the phosphine oxide-aziridinyl phosphonate POAP-A Lewis bases formed the aldol products in up to 75% yield and with 65% ee.

Enantioselective Michael addition of diethyl malonate to nitroolefins with bifunctional 2-aminodmap/urea organocatalyst Bakırcı Çetinkaya, İrem; Tanyeli, Cihangir; Department of Chemistry (2016) The enantioselective organocatalytic Michael addition reaction has gained increased attention as an asymmetric synthesis strategy for C-C bond formation. In this regard, (1R,2R)-trans-1,2-cyclohexanediamine derived C1 symmetrical 2-aminoDMAP has been synthesized in our group. The remaining primary amine was modified with 1-isothiocyanato-(3,5)-bis(trifluoromethyl) benzene 3,5-Bis (trifluoromethyl) phenyl isothiocyanate and 3,5-bis(trifluoromethyl) phenyl isocyanate to afford bifunctional 2-aminoDMAP/thioure...
