The PdCl(2)-catalyzed cyclization of amino allylic alcohol 16 gave the cyclized product 17a with excellent diastereoselectivity. The versatility of compound 17a as the building block for synthesizing cis-2,6-disubstituted piperidine alkaloids has been demonstrated by a total synthesis of (-)-cassine (1). [reaction--see text]
PdCl(2)催化的氨基烯丙醇16的环化反应使环化产物17a具有极佳的非对映选择性。通过合成(-)-酪氨酸(1)已经证明了化合物17a作为合成顺式-2,6-二取代哌啶生物碱的基础材料的多功能性。[反应-见文字]
