What is 1-Chloroisoquinoline?

Chemical properties

white to yellow low melting solid, crystals and/or

The Uses of 1-Chloroisoquinoline

Used in a Mn-catalyzed cross-coupling with aryl- and alkylmagnesium halides.1 Also used in a Pd-catalyzed cross-coupling with heteroaryl boronic acids and esters.2

The Uses of 1-Chloroisoquinoline

1-Chloroisoquinone is used in the preparation of new aminoisoquinolinylurea derivatives which show antiproliferative activity against melanoma cell lines. It can also be applied to the control of stor age and stability of unstable boronic acids.

The Uses of 1-Chloroisoquinoline

The product has been used in a Mn-catalyzed cross-coupling with aryl- and alkylmagnesium halides. It has also been used in a Pd-catalyzed cross-coupling with heteroaryl boronic acids and esters. Furthermore, it has been used in a homocoupling reaction to yield bis-isoquinoline, each enantiomer of which might be very useful as a chiral ligand for asymmetric synthesis. 1-Chloroisoquinone is used in the preparation of new aminoisoquinolinylurea derivatives which show antiproliferative activity against melanoma cell lines. It can also be applied to the control of storage age and stability of unstable boronic acids.
