Several examples of efficient catalytic conversions of cyclohexene to optically active 2-cyclohexenyl propionate are reported using t-Bu hydroperoxide as oxidant. With the bis-(S)-prolinato copper(II) complex enantioselectivities up to 63% with good conversions were obtained. A neg. non-linear ligand effect was observed Addition of catalytic amounts of anthraquinone resulted in a higher enantioselectivity as well as a reversal of the non-linear effect. This study involved multiple reactions and reactants, such as (S)-2-(4-Benzyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-92-2Product Details of 163165-92-2).
(S)-2-(4-Benzyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-92-2) belongs to oxazolidine derivatives. Oxazolidines are commonly obtained by reaction of strained heterocycles, mainly aziridines. In another report, the incorporation of an additional substituted oxazolidine ring over a range of new biphenylazepinium salt organocatalysts for the asymmetric epoxidation of alkenes improved enantiocontrol over the parent structures.Product Details of 163165-92-2
