Readily synthesised quincorine and quincoridine derived chiral diamines efficiently catalyse the asymmetric monobenzoylation of cyclic and acyclic meso-1,2-diols.
容易合成的喹啉和喹吖啶衍生手性二胺可高效催化环状和非环状介-1,2-二醇的不对称单苯甲酰化反应。
Highly efficient catalytic asymmetric acylation of meso-1,2-diols with benzoyl chloride in the presence of a chirai diamine combined with Et3N
Catalyticasymmetricacylation of meso-1,2-diols has been successfully performed by the reaction with benzoyl chloride in the presence of 0.5 mol% of chiral diamine derived from (S)-proline combined with a stoichiometric amount of triethylamine to give the corresponding monobenzoate with good to excellent enantioselectivities.
Nonenzymatic desymmetrization of cis-1,2-cyclohexanediol by the asymmetric acylation with achiral benzoyl chloride in the presence of a chiral diamine derived from (S)-proline took place to give monobenzoate in high optical yield. (C) 1997 Elsevier Science Ltd. All rights reserved.
