successful synthesis of novel spirofused spiropyrrolidine 1,3-indanedione derivatives using 1,3-dipolar cycloadditionreactions is reported. 1-Benzyl-3,5-bis[(E)-arylmethylidene]tetrahydro-4(1H)-pyridinones prepared via Knöevenagel condensation of 1-benzyl-4-piperidinone with aromatic aldehydes underwent a one-pot, three-component reaction with benzylamines and ninhydrin in ethanol to afford the desired products
A library of novel bis-spiropiperidone–tetrahydrothiophene hybrid heterocycles have been synthesized via pseudo-three-component dominoreaction of (3 E ,5 E )-3,5-bis(arylidene)-1-methyl/benzyl piperidin-4-ones and 1,4-dithiane-2,5-diol in the presence of triethylamine. This transformation presumably proceeds via two annulations each involving the generation of 2-mercaptoacetaldehyde from 1,4-dithiane-2
通过 (3 E ,5 E )-3,5-双(亚芳基)-1-甲基/苄基哌啶-4-酮的假三组分多米诺反应合成了新型双螺哌啶酮-四氢噻吩杂环化合物库和 1,4-二噻烷-2,5-二醇在三乙胺的存在下。这种转化大概是通过两个环化进行的,每个环化都涉及从 1,4-二噻烷-2,5-二醇-迈克尔加成-分子内醛醇序列生成 2-巯基乙醛,这导致在一锅操作中产生四个新键。该协议的优点是原子经济性高、立体选择性高、反应时间短、操作简单。
