Synthesis

To a solution of the bis-phosphoramide catalyst (59 mg, 0.1 mmol) in CH2Cl2 (1 mL) and diisopropylethylamine (1.0 mL) under N2 at ?78 °C was added allyltrichlorosilane (580 μL, 4.0 mmol). The solution was stirred at ?78 °C for 10 min before benzaldehyde (200 mL, 2.0 mmol) was added. The resulting mixture was stirred at this temperature for 8 h whereupon the cold solution was poured in to a mixture of saturated aqueous NaHCO3 (10 mL) and saturated aqueous KF (10 mL) at 0 °C with vigorous stirring. The mixture was stirred for 2 h at room temperature and then fifiltered through Celite. The layers were then separated and the aqueous layer was extracted with CH2Cl2 (3 × 30 mL). The combined organic extracts were dried (MgSO4), fifiltered, and concentrated. The oily residue was purifified by column chromatography (silica gel) eluting with CH2Cl2:pentane (3:1) followed by CH2Cl2 to give 254 mg (85%) of the benzylic alcohol in 87% ee.

Check Digit Verification of cas no

The CAS Registry Mumber 77118-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,1 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77118-87:
(7*7)+(6*7)+(5*1)+(4*1)+(3*8)+(2*8)+(1*7)=147
147 % 10 = 7
So 77118-87-7 is a valid CAS Registry Number.

Emergence of Highly Enantioselective Catalytic Activity in a Helical Polymer Mediated by Deracemization of Racemic Pendants

Ikai, Tomoyuki,Ando, Mitsuka,Ito, Masaki,Ishidate, Ryoma,Suzuki, Nozomu,Maeda, Katsuhiro,Yashima, Eiji

supporting information, p. 12725 - 12735 (2021/08/24)

Any polymers composed of racemic repeating units are obviously optically inactive and hence chiral functions, such as asymmetric catalysis, will not be expected at all. Contrary to such a preconceived notion, we report an unprecedented helical polymer-based highly enantioselective organocatalyst prepared by polymerization of a racemic monomer with no catalytic activity. Both the right- and left-handed helical poly(biarylylacetylene)s (PBAs) composed of dynamically racemic 2-arylpyridyl-N-oxide monomer units with N-oxide moieties located in the vicinity of the helical polymer backbone can be produced by noncovalent interaction with a chiral alcohol through deracemization of the biaryl pendants. The macromolecular helicity and the axial chirality induced in the PBAs are retained ("memorized") after complete removal of the chiral alcohol. Accordingly, the helical PBAs with dual static memory of the helicity and axial chirality show remarkable enantioselectivity (86% ee) for the asymmetric allylation of benzaldehyde. The enantioselectivity is slightly lower than that (96% ee) of the homochiral PBAs prepared from the corresponding enantiopure (R)- and (S)-monomers, but is comparable to that (88% ee) of the helical PBA composed of nonracemic monomers of ca. 60% ee.
