(R)-2′-amino-[1,1′-binaphthalen]-2-ol, cas is 137848-28-3, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,137848-28-3
General procedure: To a mixture of 3,4-dimethoxy-3-cyclobutene-1 ,2-dione (Ia) (0.2 mmol) in MeOH (0.25- 1 mL) the amine 2a-m was firstly added at room temperature. After the correspondingreaction time (ti) (see Table I), the amine 4a-n (0.2 mmol) was then added with MeOH (1.75-1 mL). After the corresponding reaction time (t2) (see Table I and Table Ibis), the product was purified by filtration or by column chromatography. Yields are reported in Table I and Table Ibis and pure compounds were obtained as stable solids.
As the rapid development of chemical substances, we look forward to future research findings about 137848-28-3
