3-Oxo-3-phenylpropanenitrile(cas: 614-16-4) has been used in the synthesis of substituted naphtho[1,8-bc]pyrans. It was also used as building block in the preparation of 4H-pyrans, 2-pyridones, furans and carbocyclics.Computed Properties of C9H7NO

Computed Properties of C9H7NOIn 2020 ,《Transition metal-free cyclization of N-Boc-N-propargylenamines》 appeared in Heterocycles.

The article conveys some information:

An efficient method for the synthesis of multi-substituted pyrroles was developed using basic cyclization of readily accessible N-Boc-N-propargylenamines. Despite the basic conditions, cleavage of the N-Boc group occurred easily. The process was rapid and afforded N-H-pyrroles with wide functional group tolerance in high yields. After reading the article, we found that the author used 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4Computed Properties of C9H7NO)
