(R) and (S)-t-butyloxirane [(R)- and (S)-3] have been prepared in high enantiomeric purity from racemic t-butyloxirane (±)-3 by an enzymatic route. (S)-3 has been used for the preparation of the chiral β-amino alcohols (R)- and (S)-1,2, which are catalysts for the enantioselective addition of dialkylzinc reagents to aldehydes.
(R)和(S)-叔丁基环氧乙烷[[ R)-和(S)-3 ]是通过外消旋的叔丁基环氧乙烷(±)-3通过酶促途径以高对映体纯度制备的。(S)-3已用于制备手性β-氨基醇(R)-和(S)-1,2,它们是将二烷基锌试剂对醛对映选择性加成的催化剂。
