Bis((R)-4-benzyl-4,5-dihydrooxazol-2-yl)methane has CAS 1646862-39-6 and molecular formula C21H22N2O2. PubChem returns one compound for this registry number, CID 20759766, with molecular weight 334.4. Its verified isomeric SMILES is C1[C@H](N=C(O1)CC2=N[C@@H](CO2)CC3=CC=CC=C3)CC4=CC=CC=C4. InChIKey FJGIVZKTXYTIHL-RTBURBONSA-N identifies the same stereochemically specified graph.
The molecule contains two 4,5-dihydrooxazole rings, each contributing one nitrogen and one oxygen. A methylene unit links their 2 positions, while each ring carries a benzyl group at position 4. The `(R)` descriptor applies to both corresponding ring stereocenters, and the isomeric SMILES encodes that paired configuration. Two phenyl rings account for the aromatic portions of the formula. Omitting the repeated stereochemical descriptor would leave an enantiomeric or mixed configuration unresolved even though the elemental composition remained unchanged.
A stereochemistry-specific inquiry to Rlavie should state CAS 1646862-39-6, the full bis-ring name, and the requested quantity. Supply a MOL or SDF structure file with chiral information so it can be compared with PubChem CID 20759766, the isomeric SMILES, and InChIKey FJGIVZKTXYTIHL-RTBURBONSA-N. Before request-specific information is discussed, the review should confirm both `(R)` ring centers, both benzyl attachments, and the methylene bridge between the two heterocycles. A non-isomeric sketch or the phrase “bis(benzyl oxazoline)” does not preserve the two configured centers and is therefore not an equivalent identity reference.
