Product Details of 71432-55-8In 2014 ,《Enantioselective total synthesis of (-)-scabronine D》 was published in Heterocycles. The article was written by Kobayakawa, Yu; Nakada, Masahisa. The article contains the following contents:
An enantioselective total synthesis of (3aS,5aR,6R,9R,10aR)-8-[(benzoyloxy)methyl]-3,4,5,5a,6,9,10,10a-octahydro-6-hydroxy-5a-methyl-1-(1-methylethyl)-6,9-epoxycyclohept[e]indene-3a(2H)-carboxylic acid [(-)-scabronine D diterpenoid] a which contains bridged hemiacetal group is described. The synthesis of the target compound was achieved using an enantiopure intermediate which was previously reported for a total synthesis of scabronine G and scabronine A and (-)-episcabronine A. Because the advanced intermediate was found to be sensitive to basic reaction conditions, the C14 keto and C11 hydroxy groups had to be co-protected as Me acetal. In addition, both the C15 hydroxy and C17 carboxyl groups were too reactive to be chem. discriminated; hence, the carboxyl group once formed was protected as a tert-Bu ester for ensuring successful transformations. In the experimental materials used by the author, we found tert-Butyl N,N’-diisopropylcarbamimidate(cas: 71432-55-8Product Details of 71432-55-8)
tert-Butyl N,N’-diisopropylcarbamimidate(cas: 71432-55-8) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Product Details of 71432-55-8
