Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. 122775-35-3, formula is C8H11BO4, Name is 3,4-Dimethoxyphenylboronic acid. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3. Product Details of C8H11BO4.
Choi, Hosam;Choi, Joohee;Han, Jongyeol;Lee, Kiyoun research published 《 Divergent Total Syntheses of Gymnothelignan N, Beilschmin A, and Eupomatilones 1, 3, 4, and 7》, the research content is summarized as follows. A seven-step asym. total synthesis of gymnothelignan N is detailed in the current report. The approach is based on an early-stage one-carbon homologative lactonization reaction, which we recently revisited and modified to construct the core γ-butyrolactone motif with the requisite β,γ-vicinal stereogenic centers. By design, the utilization of the same chiral γ-butyrolactone intermediate permitted the rapid and effective divergent assembly of optically active eupomatilones 1, 3, 4, and 7 in five or six steps from com. available materials. This represents one of the shortest and highest-yielding syntheses reported to date.
