Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 36620-11-8, is researched, SMILESS is [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10, Molecular C14H8BF4RhJournal, Chinese Chemical Letters called Facile access to chiral 4-substituted chromanes through Rh-catalyzed asymmetric hydrogenation, Author is Tao, Lin; Zhao, Qingyang; Zhang, Xumu; Dong, Xiu-Qin, the main research direction is chromane preparation enantioselective; chromanylidene acetate asym hydrogenation rhodium catalyst.Category: quinuclidine.
Rh/ZhaoPhos-catalyzed asym. hydrogenation of a series of (E)-2-(chroman-4-ylidene)acetates I (R = H, Cl, F, MeO; R1 = CO2Me, CO2Et, CO2iPr) was successfully developed to prepare various chiral 4-substituted chromanes II with high yields and excellent enantioselectivities (up to 99% yield, 98% ee). Moreover, the gram-scale hydrogenation could be performed well in the presence of 0.02 mol% catalyst loading (TON = 5000) and the hydrogenation product II (R = H, R1 = CO2Et) was easily converted to access other important compounds, II (R = H, R1 = CO2H, CH2OH) which demonstrated the synthetic utility of this asym. catalytic methodol.
