(1R,4′S)-4-(tert-Butyldimethylsilanoxy)-1-[2,2-dimethyl-3-(p-tolylsulfonyl)-1,3-oxazolidin-4-yl]but-2-yn-1-ol
The chiral title compound, C(22)H(35)NO(5)SSi, is a precursor of novel furanomycin derivatives. It crystallizes with two molecules in the asymmetric unit; these show different conformations of the silyl substitutent, as indicated by the Si—O—C—C torsion angles of 41.4 (7) and −84.5 (5)° in the two...

Sumario: | The chiral title compound, C(22)H(35)NO(5)SSi, is a precursor of novel furanomycin derivatives. It crystallizes with two molecules in the asymmetric unit; these show different conformations of the silyl substitutent, as indicated by the Si—O—C—C torsion angles of 41.4 (7) and −84.5 (5)° in the two molecules. The anti configuration of the adjacent stereogenic centers is consistent with the Felkin–Anh model. Each of the two crystallographically independent molecules is connected with a neighbouring molecule of the same type via two symmetry-equivalent O—H⋯O hydrogen bonds. |
