A general two-step procedure for the reduction of indoles to the corresponding 4,5,6,7-tetrahydroindoles has been developed. A regioselective Birch reduction followed by catalytic hydrogenation is employed to accomplish this transformation. Yields for the sensitive pyrrole products are typically between 40 and 50%. This method provides access to complex chiral pyrroles that cannot be readily prepared
已经开发了将吲哚还原为相应的4,5,6,7-四氢吲哚的通用两步方法。使用区域选择性的桦木还原,然后进行催化氢化来完成该转化。敏感的吡咯产物的产率通常在40%至50%之间。该方法提供了难以通过其他方法制备的复杂手性吡咯的途径。
