The invention relates to a process for the manufacture of acid halides from aldehydes, characterised in that it consists in reacting at least one aldehyde, free of amino functional group and of hydroxyl functional group, with at least one di- or trihalocyanuric acid or the salts of the di...
A process for efficiently producing aryl formate and aromatic carboxylic acid from aldehyde, which comprises oxidizing an aromatic aldehyde with an oxygen-containing gas in the presence of a volatile solvent up to a reaction ratio of 40 to 70 mol% to convert the aromatic aldehyde to a peracid,...

Acid hydrolysis of the dimethyl acetal function provided aldehyde 80. Reaction of aldehyde 80 with chiral sulfone 81, prepared from (E)-2-butene-1,4-diol by the Sharpless asymmetric epoxidation, afforded a coupling product. After oxidation of the hydroxy group, the sulfonyl group was removed by...
Disclosed is hylan, a chemically modified hyaluronic acid preparation characterized by the presence of small amounts (0.005-0.05% by weight) of aldehyde cross-linking groups covalently bonded to the hyaluronic acid molecular chains. Also disclosed is a method of obtaining hylan comprising treating hyal...

The utility of L-TAs for the enzymatic synthesis of L-threo-b- hydroxy-a-amino acids from an aldehyde and glycine has been extensively investigated, but is limited due to low synthetic yields and modest diastereoselectivity10,11. The low yields are in part due to the reversible nature of ...
