摘要：

Three's a crowd: The title reaction provides a tetracylic core bearing three chiral centers (see scheme; Ts=4-toluenesulfonyl) with excellent enantioselectivity and good diastereoselectivity. The reaction was used to efficiently construct the (+)-kreysiginine skeleton. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
