A series of parallel reactions were carried out for the tandem Ugi/Diels–Alder reaction on our MPEG–O–CH2- platform. Ninety-six out of a 100 entries were successful to give complex heterotricycles. The stereoselectivity was found not to be influenced by the building blocks used for amine and carboxylic acid components. An unexpected side pathway was found but was suppressed by employing appropriate
在我们的MPEG-O-CH 2-平台上,针对串联Ugi / Diels-Alder反应进行了一系列平行反应。在100个条目中,有96个成功生成了复杂的杂环。发现立体选择性不受用于胺和羧酸组分的结构单元的影响。发现了意外的旁通路,但是通过采用适当的反应条件可以抑制这种旁通路。该反应也在固相上进行,通过采用分流池法,可以潜在地实现更大的文库。
