Synthesis of diazirines
A number of methods exist in the literature for the preparation of diazirines, which begin from a variety of reagents. Synthesis from ketones Generally, synthetic schemes that begin with ketones (>C=O) involve conversion of the ketone with the desired substituents to diaziridines (>CN2H2). These … See more In organic chemistry, diazirines are a class of organic molecules consisting of a carbon bound to two nitrogen atoms, which are double-bonded to each other, forming a cyclopropene-like ring, 3H-diazirene (>CN2). They are See more Upon irradiation with UV light, diazirines form reactive carbene species. The carbene may exist in the singlet form, in which the two free … See more Diazirines are often used as photoreactive crosslinking reagents, as the reactive carbenes they form upon irradiation with UV light can insert into C-H, N-H, and O-H bonds. This results … See more Webthis manuscript, we describe the design and synthesis of two new photo-crosslinking reagents that can be used to specifically label free thiols through either maleimido or methanethiosulfonate groups and facilitate PXL-MS workflows. Both crosslinkers are based on light sensitive diazirines – precursors of
