Ahmed, Mahmood published the artcileA tripartite asymmetric allylboration – silicon tethered alkene ring closing metathesis – in situ ring opening protocol for the regiospecific generation of functionalized (E)-disubstituted homoallylic alcohols, Application of (+)-B-Methoxydiisopinocampheylborane, the publication is Tetrahedron (1999), 55(11), 3219-3232, database is CAplus.
Molybdenum carbene I catalyzed ring closing metathesis of (alkenyl)silyl ethers of homochiral allylic alcs., e.g. II, to afford 1,2-oxasilines, e.g. III, which were elaborated in situ to give (E)-4-alkyl-1,2- disubstituted 3-buten-1-ol and (Z)-4-alkyl-4-silyl-1,2-disubstituted 3-buten-1-ol derivatives as single geometric isomers.
Tetrahedron published new progress about 99438-28-5. 99438-28-5 belongs to ethers-buliding-blocks, auxiliary class Chiral,Aliphatic cyclic hydrocarbon, name is (+)-B-Methoxydiisopinocampheylborane, and the molecular formula is C21H37BO, Application of (+)-B-Methoxydiisopinocampheylborane.
