通过将磺胺稳定的碳负离子完全选择性地在分子内加成到α,β-不饱和酯上,苯并噻嗪以对映体纯的形式容易获得,可以以良好的总收率转化为麦角豆烯的前体。(C)2005爱思唯尔有限公司。保留所有权利。
A benzothiazine, readily available in enantiomerically pure form via a completely selective, intramolecular addition of a sulfoximine-stabilized carbanion to an alpha, beta-unsaturated ester, could be converted to a precursor to erogorgiaene in good overall yield.
