摘要：

The cycloaddition of (Z) and (E)-vinyl sulfoxides with cyclic nitrones 1 and 2 is reported. Best diastereoselection is achieved with (Z)-vinyl sulfoxides 7a-d as dipolarophiles. This methodology allows the highly stereoselective synthesis of (+)-sedridine 9a, (-)-hygroline 10 and (-)-(2S)-N-carbomethoxypelletierine 11a. (C) 1997, Elsevier Science Ltd. All rights reserved.
