Reaction of the dimers [RuCl2(η6-arene)]2 (arene = mesitylene a, p-cymene b, C6H6 c) with salicyloxazolines in the presence of NaOMe gives the corresponding [RuCl(R,R’-saloxaz)(arene)] (R = R’ = Me 1; R = H, R’ = Me2CH 2, Me3C 3, PhCH2 4, Ph 5), which were fully characterized. [RuL(iPr-saloxaz)(mes)]Y (L = py 6, 2-Mepy 7, 4-Mepy 8, PPh3 9; Y- = SbF6 or BPh4) were prepared by treating the chloride 2a with ligand L and NaY (Y- = SbF6 or BPh4) in MeOH at reflux. Halide complexes [RuX(iPr-saloxaz)(mes)] (X = Br, 10; X = iodo, 11) were synthesized by treating 2a with AgSbF6 then with 1.2 equiv KBr or NaI, whereas the Me complex [RuMe(iPr-saloxaz)(mes)] 12 was synthesized from 2a by reaction with MeLi. Five complexes, [RuCl(iPr-saloxaz)(mes)] 2a, [RuCl(tBu-saloxaz)(p-cymene)] 3b, [RuCl(Ph-saloxaz)(mes)] 5a, [Ru(4-Mepy)(iPr-saloxaz)(mes)][SbF6] 7, and [Ru(PPh3)(iPr-saloxaz)(mes)][SbF6] 9, were characterized by x-ray crystallog. Treatment of complexes 1-5 with AgSbF6 gives cationic species which are enantioselective catalysts for the Diels-Alder reaction of acroleins with cyclopentadiene, and the effect of substituents on enantioselectivity was examined This study involved multiple reactions and reactants, such as 2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1SDS of cas: 163165-91-1).
2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1) belongs to oxazolidine derivatives.Oxazolidines are readily available also from propargyl amines. Chiral oxazolidines are widely used as chiral auxiliaries, chiral ligands, protecting and/or directing groups in a variety of asymmetric transformations, thanks also to their easy cleavage or their further elaboration possibilities.SDS of cas: 163165-91-1
