Recommanded Product: 20880-92-6On November 23, 2020 ,《Enantioselective Silylation of Aliphatic C-H Bonds for the Synthesis of Silicon-Stereogenic Dihydrobenzosiloles》 appeared in Angewandte Chemie, International Edition. The author of the article were Yang, Bo; Yang, Wu; Guo, Yonghong; You, Lijun; He, Chuan. The article conveys some information:
A Rh(I)-catalyzed enantioselective silylation of aliphatic C-H bonds for the synthesis of Si-stereogenic dihydrobenzosiloles is demonstrated. This reaction involves a highly enantioselective intramol. C(sp3)-H silylation of dihydrosilanes, followed by a stereospecific intermol. alkene hydrosilylation leading to the asym. tetrasubstituted silanes. A wide range of dihydrosilanes and alkenes displaying various functional groups are compatible with this process, giving access to a variety of highly functionalized Si-stereogenic dihydrobenzosiloles in good to excellent yields and enantioselectivities. After reading the article, we found that the author used ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6Recommanded Product: 20880-92-6)
((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6) is a useful reactant for examining the effectiveness of sulfamate and sulfamide groups for the inhibition of carbonic anhydrase-II (CA-II).Recommanded Product: 20880-92-6 And it is used as chiral auxiliaries in Michael and Aldol addition reactions.
