Three chiral vinyldioxazaborocanes.
The structures of three chiral vinyldioxazaborocanes are reported, namely (2E)- and (2Z)-6-benzyl-2-buten-2-yl-1,3,6,2-dioxazaborocane, C27H30BNO2, (II) and (III), respectively, and (2Z)-2-buten-2-yl-6-isobutyl-1,3,6,2-dioxazaborocane, C24H32BNO2, (IV). These compounds may be useful in asymmetric reactions. In the structures reported here, the N-B donor-acceptor bond is longer than in any previously reported analogous compounds.
