AN ACETAL GROUP SUITABLE FOR THE PROTECTION OF 2'-HYDROXY FUNCTIONS IN RAPID OLIGORIBONUCLEOTIDE SYNTHESIS

Reese, Colin B.,Serafinowska, Halina T.,Zappia, Giovanni

, p. 2291 - 2294 (2007/10/02)

The 1--4-methoxypiperidin-4-yl has an acid lability similar to that of the 4-methoxytetrahydropyran-4-yl (Mthp) protecting group under mild hydrolytic conditions ; however, under the relatively more drastic conditions required for the complete removal of a 9-phenylxanthen-9-yl (Px) group, the Ctmp protecting group remains virtually intact.
