New syntheses of (−)-deoxoprosophylline, (+)-2-epi-deoxoprosopinine, and (2R,3R)- and (2R,3S)-3-hydroxypipecolic acids are reported. Utilization of the chiral functionalities of Perlin aldehydes, derived from 3,4,6-tri-O-benzyl glycals, has been done along with chemoselective saturation of olefins and reductive aminations as key steps.
报道了(-)-脱氧脯氨酸,(+)-2-表-脱氧胸苷,(2 R,3 R)-和(2 R,3 S)-3-羟基哌酸的新合成。衍生自3,4,6- tri - O-苄基缩醛的Perlin醛的手性官能团已被用作主要步骤,同时对烯烃进行了化学选择性饱和和还原性胺化反应。
