The alkaloids (±)-cryptopleurine 1, (±)-antofine 2, and (±)-deoxypergularinine 3 were synthesized by Pictet-Spengler cyclization of the 2-arylmethylpiperidine and -pyrrolidines 4, 5 and 6 obtained by sequential N-deprotection-reduction of the parent enecarbamates 7, 8 and 9. These latter were made by the Horner reaction of phosphorylated carbamates 12 and 13 with the appropriate aldehydes 10 and 11
生物碱(±)-cryptopleurine 1,(±)-antofine 2,和(±)-deoxypergularinine 3是由2- arylmethylpiperidine的的Pictet Spengler环化生成合成并-pyrrolidines 4,5和6通过顺序获得Ñ -deprotection-还原母体氨基甲酸酯7、8和9。后者是通过磷酸氨基甲酸酯12和13与适当的醛10和11的霍纳反应制得的。
