, p. 5030 - 5033 (2012/11/07)
Propylphosphonic anhydride (T3P), a low toxic peptide coupling agent, has been demonstrated to be an efficient catalyst for the chemoselective acetalization and thioacetalization of aldehydes in the presence of ketones. Cyclic and acyclic acetals of diverse aldehydes were obtained in good to excellent yields at room temperature in the presence of a catalytic amount of T3P.

experimental part, p. 873 - 876 (2012/04/05)
Carbonyl compounds were converted to the corresponding 1,3-dioxolanes and 1,3-dioxanes with ethylene glycol and 1,3-propandiol in the presence of bismuth triflate under solvent-free conditions. In addition, high chemoselective protection of aldehydes in the presence of ketones has been achieved.

Origin of selectivity in the antibody 20F10-catalyzed Yang cyclization
Saphier, Sigal,Hu, Yunfeng,Sinha, Subhash C.,Houk,Keinan, Ehud
, p. 132 - 145 (2007/10/03)
The first antibody-catalyzed Yang (Norrish type II) cyclization has been achieved with antibodies that were elicited against cis- and trans-2,3-diaryloxetanes. The photocyclization of 1,4-diarylbutan-1-one produced a single stereoisomer of cis-1,2-diarylc
ALUMINA AS AN VERSATILE CATALYST FOR THE SELECTIVE ACETALIZATION OF ALDEHYDES
Kamitori, Yasuhiro,Hojo, Masaru,Masuda, Ryoichi,Yoshida, Tatsushi
, p. 4767 - 4770 (2007/10/02)
Alumina was found to be an effective and convenient catalyst for acetalization of aldehydes to the corresponding 1,3-dioxoranes and 1,3-dioxanes.It can be used for selective protection of only formyl group of ketoaldehydes.
APPLICATION OF THE COMBINATION OF SODIUM BISULFITE AS A PROTECTIVE REAGENT AND SOLID SUPPORTS IN THE SELECTIVE REDUCTION OF 4-ACETYLBENZALDEHYDE WITH DIBORANE
Chihara, Teiji,Wakabayashi, Tamie,Taya, Kazuo
, p. 1657 - 1660 (2007/10/02)
4-Acetylbenzaldehyde (2) has been selectively reduced by using a combination of protective group and solid supports.The formyl group of 2 was protected by addition of sodium bisulfite.The adduct, supported on silica gel, was then selectively reduced to 4-
