Keywords: kinetic resolution rhodium catalyzed carbon carbon activation cyclobutanone; trans fused bicycle cyclobutanone enantioselective synthesis DFT.They researched the compound: 1-Bromo-2-pentyne( cas:16400-32-1 ).Related Products of 16400-32-1. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:16400-32-1) here.
Herein we describe the development of a highly selective kinetic resolution of cyclobutanones via a Rh-catalyzed “”cut-and-sew”” reaction with selectivity factor up to 785. This reaction takes place at room temperature with excellent efficiency. Various trans-5,6-fused bicycles and C2-substituted cyclobutanones were obtained with excellent ee’s that can be further used as chiral building blocks. DFT calculations reveal the crucial roles of the DTBM-segphos ligand in stabilizing the rate- and enantioselectivity-determining C-C oxidative addition transition state via favorable ligand-substrate dispersion interactions.
