-
Paragraph 0215-0218, (2019/02/10)
The invention relates to a method for visible light driven green synthesis of benzoin bis-ether. The method comprises the steps that an alkyne compound, an alcohol compound and 10-methyl-9-sym-trimethylbenzene based acridine perchlorate perform driving reaction in the atmosphere at room temperature with the visible light with the wavelength of 450-460 nm, a reaction solution is obtained after 3 hours and is spin-dried to obtain concentrate, and the concentrate is subjected to column chromatography on silica gel to obtain the benzoin bis-ether. The method is high in yield, moderate in conditionand small in environmental pollution.

Reaction of aliphatic α-hydroxy esters with azodicarboxylates and triphenylphosphine in the presence of either CbzNHOCH2Ph or trOCNHOCH2Ph provides a direct route to protected α-N-hydroxy amino acids.Similar reactions with aromatic α-hydroxy carbonyl compounds and derivatives result in predominate oxidation to the corresponding α-oxo carbonyl derivatives.
