Disclosed herein are mono- and di-substituted tetrazines and methods of their preparation and converting an oxetanyl ester to a thio-substituted tetrazine, which is then converted to a mono-substituted tetrazine, a di-substituted tetrazine, or a vinylether disubstituted tetrazine.

Reagents and methods for tetrazine synthesis

A method for catalytically converting a dihydrotetrazine 1 into a tetrazine 2, wherein one R group on the dihydrotetrazine 1 is a substituted or unsubstituted aryl, heteroaryl, alkyl, alkenyl, alkynyl, carbonyl, or heteroatom-containing group, and the other R group is selected from the group consisting of H and substituted or unsubstituted aryl, heteroaryl, alkyl, alkenyl, alkynyl, carbonyl,- or heteroatom-containing groups; 1, 2 wherein the method comprises oxidizing dihydrotetrazine 1 in a reaction medium in the presence of a catalyst and a stoichiometric oxidant. 

Methods for inducing bioorthogonal reactivity

A substituted trans-cycloheptene according to formula (I); wherein: a) Z and L are each selected from the group consisting of SiRR, CH, CHOH, and CHR; Ris phenyl or CH; Ris phenyl, CH, (CH)CN, or (CH)OH, wherein n is an integer from 1 to 5; Rand Rare each individually selected from the group consisting of H, OH, and CH; and Z and L are not both SiRR; or b) Z is BocN, L is CH, Ris H, and Ris H; or c) Z is C=0, L is CH, Ris H, and Ris H.
