Asymmetric addition of isocyanate compounds on chiral
triquinphosphoranes, tricyclic hydridophosphoranes, led by a total
diastereoselective opening of the diazaphospholidine ring. This provides
chiral bicyclic oxazaphospholidines in which an eight-membered ring is
fused to the oxazaphospholidine ring by the P–N bond.
异氰酸酯化合物与手性三
喹啉磷烷、
三环氢化物磷烷的不对称加成,导致重氮膦环的完全非对映选择性打开。这样就得到了手性双环
噁唑磷烷,其中一个八元环通过 P-N 键与
噁唑磷啶环融合。
