, p. 15538 - 15540 (2018)
The synthesis of pyridoxal acetal salts and the controlled-release of the alcohols in the presence of neutral pH water is described. The rate of release was monitored by1H NMR and was found to be dependent on the concentration of water in the sample. The acetal salts are stable in the absence of moisture and show promise as a vitamin-based pro-fragrance delivery system.

Pyridoxal in the absence of catalyst forms furo[3,4-c]pyridine species (ortho aldehyde and hydroxymethyl groups are involved) which is further transformed into C–C hybrid with 4-hydroxycoumarin. Different products of chromeno-[3′,4′:5,6]pyrano[2,3-c]pyrid

Paragraph 0049; 0050, (2019/08/12)
A pro-fragrance delivery system based on a vitamin scaffold and a fragrant alcohol. The vitamin scaffold may be a vitamer of vitamin B6 or derivatives thereof. The pro-fragrance releases the fragrant alcohol by action of water at neutral pH.

Kibardina, Lyudmila K.,Trifonov, Alexey V.,Dobrynin, Alexey B.,Pudovik, Michael A.,Burilov, Alexander R.,Sinyashin, Oleg G.
, p. 221 - 227 (2016/07/21)
The products of carbonyl phosphonylation of pyridoxal with dialkylphosphinous acid, alkylphosphinic acid ethyl esters, and phosphorous acid dialkyl (or diphenyl) esters have been obtained for the first time. In some cases, the products of addition are hyd
