  Synthesis of a Family of Spirocyclic Scaffolds: Building Blocks for the Exploration of Chemical Space

  摘要：

  This report describes the preparation Of a series of 17 novel racemic spirocyclic scaffolds that are intended for the creation of compound libraries by parallel synthesis for biological screening. Each scaffold features two points of orthogonal diversification. The scaffolds are related to each other in four ways: (1) through stepwise changes in the size of the nitrogen-bearing ring; (2) through the oxidation state of the carbon-centered point of diversification; (3) through the relative stereochemical orientation of the two diversification sites in those members that are stereogenic; and (4) through the provision of both saturated and unsaturated versions of the furan ring in the scaffold series derived from 3-piperidone. The scaffolds provide incremental changes in the relative Orientation of the diversity components that would be introduced onto them. The scaffolds feature high sp(3) carbon content which is essential for the three-dimensional exploration Of chemical space. This characteristic is particularly evident in those members of this family that bear two stereocenters, i.e., the two series derived from 3-piperidone and 3-pyrrolidinone. In the series derived from 3-piperidone we were able to "split the difference" between the two diastereomers by preparation of their corresponding unsaturated version.

  Skeletal Diversification via Heteroatom Linkage Control: Preparation of Bicyclic and Spirocyclic Scaffolds from N-Substituted Homopropargyl Alcohols

  摘要：

  The discovery and application of a new branching pathway synthesis strategy that rapidly produces skeletally diverse scaffolds is described. Two different scaffold types, one a bicyclic iodo-vinylidene tertiary amine/tertiary alcohol and the other, a spirocyclic 3-furanone, are each obtained using a two-step sequence featuring a common first step. Both scaffold types lead to intermediates that can be orthogonally diversified using the same final components. One of the scaffold types was obtained in sufficiently high yield that it was immediately used to produce a 97 compound library.
