The catalytic enantioselective synthesis of a range of cis-pyrrolizine carboxylate derivatives with outstanding stereocontrol (14 examples, >95 : 5 dr, >98 : 2 er) through an isothiourea-catalyzed intramolecular Michael addition-lactonisation and ring-opening approach from the corresponding enone acid is reported. An optimised and straightforward three-step synthetic route to the enone acid starting
通过异硫脲催化的分子内迈克尔加成-内酯化和开环方法,催化对映选择性合成一系列具有出色立体控制性的顺式吡咯嗪羧酸盐衍生物(14个实例,>95 : 5 dr,>98 : 2 er )据报道烯酮酸。描述了一种从容易获得的吡咯-2-甲醛中制备烯酮酸起始材料的优化且简单的三步合成路线,其中苯并四咪唑(5 mol%)被证明是对映选择性过程的最佳催化剂。用MeOH或一系列胺对吡咯嗪二氢吡喃酮产物进行开环,以优异的收率和对映选择性获得所需的产物。计算已被用来探索导致高立体控制的因素,所观察到的顺式立体异构体的形成预计在动力学和热力学上是有利的。

The present invention relates to certain 4-heteroaryl-3-heteroarylidenyl-2-indolinones compounds and their physiologically acceptable salts which modulate the activity of protein kinases (“PKs”), in particular CDK2. The compounds of the present invention are therefore useful in treating disorders related to abnormal PK activity. Pharmaceutical composition containing these compounds and methods of preparing these compounds are also described.

evolution of a synthetic program aimed at accessing the flagship metabolites curvulamine and curindolizine which are presumably a dimer and trimer of a C10N biosynthetic building block, respectively. Starting with curvulamine, we detail several strategies to merge two simple, bioinspired fragments, which while ultimately unsuccessful, led us toward a pyrroloazepinone building block-based strategy and an improved
