We report a base-promoted cyclization with indene-dienes as two carbon building blocks toward diverse spirocyclic indene scaffolds including hexacyclic spiroindenes bearing benzo pyran motifs and pentacyclic spiroindenes containing oxindole units in high yields with excellent diastereoselectivities.

通过以茚二烯作为两种碳结构单元环化来区域选择性和非对映选择性合成多种螺环茚
我们报道了以茚二烯作为两种碳结构单元的碱促进环化,以形成多种螺环茚支架,包括带有苯并吡喃基序的六环螺茚和含有羟吲哚单元的五环螺茚,其产率高且具有优异的非对映选择性。
