Novel non-nucleoside solid supports and phosphoramidite building blocks for preparation of synthetic oligonucleotides containing at least one non-nucleosidic moiety conjugated to a ligand of practical interest and synthetic processes for making the same are disclosed. Furthermore, oligomeric compounds are prepared using said solid supports and phosphoramidite building blocks, preferably followed by removal of protecting groups to provide oligonucleotides conjugated to ligands of interest.

an analogous protocol for alkyne substrates is yet to be developed. Herein, a base and cobalt relay catalytic process for the selective synthesis of (Z)-2-alkenes and conjugated E alkenes by migratory hydrogenation of terminalalkynes is disclosed. Mechanistic studies support a relay catalytic process involving a sequential base-catalyzed isomerization of terminalalkynes and cobalt-catalyzed hydrogenation

A syn‐selective aza‐aldol reaction of boron aza‐enolates, generated from N‐sulfonyl‐1,2,3‐triazoles and 9‐BBN‐H, is reported. It provides a sequential one‐pot procedure for the stereoselective construction of 1,3‐amino alcohols, having contiguous stereocenters, starting from terminal alkynes.

Palladium‐catalyzed cross‐coupling reactions of 1,1‐diboronates with vinylbromides and dibromoalkenes were found to afford 1,4‐dienes and allenes, respectively. These reactions utilize the high reactivities of both 1,1‐diboronates and allylboron intermediates generated in the initial coupling.
