Bhajammanavar, Vinod; Mallik, Sumitava; Choutipalli, Venkata Surya Kumar; Subramanian, Venkatesan; Baidya, Mahiuddin published an article in 2022, the title of the article was Diastereoselective access to [4,4]-carbospirocycles: governance of thermodynamic enolates with an organocatalyst in vinylogous cascade annulation.Recommanded Product: 2510-01-2 And the article contains the following content:
A vinylogy concept driven annulation strategy was developed to access [4,4]-carbospirocycles from alkylidene malononitriles and cyclopentene-1,3-diones. The reaction was catalyzed by an inexpensive organocatalyst and products with three stereocenters were obtained as a single diastereomer in high yields. The spiro-selectivity originated from the reaction of the thermodn. enolate intermediate which is fundamentally intriguing. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Recommanded Product: 2510-01-2
