intermolecular C-Hinsertion of the nitrene derived from 2,2,2-trichloroethyl-N-tosyloxycarbamate proceeded in good to excellent yields to produce a variety of Troc-protected amines. With cyclic aliphatic alkanes, it is possible to use only 2 equiv of substrate, whereas the reaction with aromatic alkanes is run neat. Not only does the nitrene insertion proceed in benzylic, secondary, and tertiary C-H bonds

strategy for the design of C–N bond formation reactions under mild reaction conditions, the challenge being lack of selectivity as a free nitrene reactive intermediate is usually involved. Herein is described an iron(III) porphyrin catalysed sp3 C–H amination and alkene aziridination with selectivity by using organic azides as the nitrogen source under blue LED light (469 nm) irradiation.

The present invention relates to a process for the preparation of the chiral compound of formula (V), wherein R1 is a C1-C6 alkyl group optionally substituted with halogens, an aryl optionally substituted, or a trialkyl silyl group, for use as an intermediate in the preparation of (R)-1-amino indanes, helpful in the pharmaceutical field. The compound of formula (V) is a key intermediate to the preparation of (R)-1-aminoindanes, particularly Rasagiline. The invention also relates to novel compounds, which are especially useful as intermediates for the preparation of (R)-1-aminoindanes.
