DNA-encoded compound libraries are widely used in drug discovery. Screening of catalysts for compatibility with solid phase-coupled DNA sequences guided the selection of encoded reactions, exemplified by a Zn(II)-mediated aza-Diels–Alder reaction.

A solid-phase synthesis of dexoxadrol analogues like-13 and unlike-13 bearing an oxo group in the 4-position of the piperidine ring has been developed using aminomethyl substituted polystyrene resin as solid support. The synthesis comprises a hetero-Diels–Alder reaction of imine 7b with Danishefsky’s diene 8 in the presence of the Lewis acid Yb(OTf)3 and a conjugate reduction of the double bond of 9b with LiBHEt3 and BF3. The cleavage of the product from the solid support was performed with 1-chloroethyl chloroformate. All transformations on the solid support and additionally the cleavage reaction had to be compatible with the large and acid labile acetalic 1,3-dioxolane moiety in 2-position of the piperidine ring. The oxodexoxadrol derivative 12 was obtained in an overall yield of 17 %.
