β¦ Synopsis
The treatment of N-benzylated heterocycles with potassium tert-butoxide/DMSO and oxygen at room temperature cleanly affords N-debenzylated products in high yield. This procedure can be utilized on a variety of functionalized nitrogen-containing heterocycles such as imidazoles, benzimidazoles, pyrazoles, indazoles, carbazoles, and indoles.

An efficient method for the palladium mediated hydrogenation of an optically active, N-protected aminooxetane derivative has been developed. Using appropriate solvents, in a one-step reaction, a chiral 1,4-aminoalcohol derivative [(2S,3R)-4-amino-3-benzoyloxy-2-benzylbutan-1-ol] was formed over a Pd
