The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate(SMILESS: [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10,cas:36620-11-8) is researched.COA of Formula: C14H8BF4Rh. The article 《Rhodium-catalyzed intramolecular hydroacylation of 1,2-disubstituted alkenes for the synthesis of 2-substituted indanones》 in relation to this compound, is published in Tetrahedron. Let’s take a look at the latest research on this compound (cas:36620-11-8).
The intramol. hydroacylation of 1,2-disubstituted alkenes was considered to be a challenging task due to the side reactions resulted from the lack of addnl. substituent at 1-position and the low activity caused by the steric hindrance of substituent at 2-position, and an asym. version was not considered possible due to problems associated with the racemization of the products. The authors have partially solved these problems. Catalyzed by an activated diphosphine-Rh complex and reacted in a selected dihalogenated solvent, the intramol. hydroacylation of o-(2-arylvinyl)benzaldehydes provided the corresponding 2-aryl-1-indanones in high yields, and its asym. variant using o-(2-alkylvinyl)benzaldehydes afforded chiral 2-alkyl-1-indanones in high yields and with moderate enantioselectivities.
