alternatives to side-chain protection and deprotection in solid-phase peptide synthesis (SPPS). Several protectinggroups have been endorsed as suitable candidates, but finding a greener protectinggroup in SPPS has been challenging. Here, based on the 2-(o-nitrophenyl) propan-1-ol (Npp-OH) photolabileprotectinggroup, a structural modification was carried out to synthesize a series of derivatives. Through experimental

Ionic diamine rhodiumcomplex (1) catalyzes the reductive N-cyclization of 2-vinylnitroarenes using carbon monoxide as a reducing agent to afford functionalized indoles. The catalytic system allows direct access to indoles with ester and ketone groups at the 2- or 3-position, in good yields.
