(S)-tert-Butyl 3-(3-phenyl-1,2,4-oxa-diazol-5-yl)piperidine-1-carboxyl-ate.

ABSTRACT: The title compound, C(18)H(23)N(3)O(3), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The phenyl ring and the 1,2,4-oxadiazole ring are inclined to one another by 19.9?(3)° in mol-ecule A and 7.3?(3)° in mol-ecule B. The absolute structure of the title compound was referred to the transfered chiral center (S) of one of the starting reacta-nts. In the crystal, A mol-ecules are linked by C-H?N inter-actions involving the two oxadiazole N atoms.

The title compound, C(18)H(23)N(3)O(3), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The phenyl ring and the 1,2,4-oxadiazole ring are inclined to one another by 19.9 (3)° in mol-ecule A and 7.3 (3)° in mol-ecule B. The absolute structure of the title compound was referred to the transfered chiral center (S) of one of the starting reacta-nts. In the crystal, A mol-ecules are linked by C-H⋯N inter-actions involving the two oxadiazole N atoms. ...[more]
