(1S,5R)-(−)- and (1R,5S)-(+)-7-phenyl-3-borabicyclo[3.3.1]non-6-enes of 97–98% de that differed only by the location of the double bond were prepared by the resolution of diastereomeric intramolecular chelates with l- and d-prolinol. Deboronation of chiral bicyclic boranes obtained was used for synthesis of optically active 3,5-dimethyl- and 3,5-dihydroxymethyl-1-phenylcyclohexenes.
(1 S,5 R)-(-)-和(1 R,5 S)-(+)-7-苯基-3-borabicyclo [3.3.1] non-6-enes的97–98%差异仅通过双键的位置通过用l-和d-脯氨醇拆分非对映体分子内螯合物来制备。将获得的手性双环硼烷脱硼用于合成光学活性的3,5-二甲基-和3,5-二羟甲基-1-苯基环己烯。
