chirality can influence the formation of an adjacent spiroketal stereocenter. Appropriately functionalized enantiomerically pure 1- and 2-sulfinyl 1,3-dien-5-ones and their corresponding iron(0) tricarbonyl complexes (7, 17) have been prepared, and the derived spiroketals (8, 18) are made in good to excellent diastereoselectivity. A preliminary exploration of the combined effects of planar and central
已经证明平面手性的元素可以影响相邻的螺状立体中心的形成。适当官能化对映体纯1-和2-亚磺酰基-1,3-二烯-5-酮和它们相应的
铁(0)三羰基复合物(7,17)已经被制备,并且所导出spiroketals(8,18)以良好的制具有出色的非对映选择性。对平面和中心手性对非对映选择性的综合影响的初步探索揭示了匹配和不匹配的组合(14)。
