ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.

introduction	12-hydroxy -4,7,10-tert-butyl trioxacate is an organic intermediate, which can be composed of 2,2 '-(ethane -1, 2-Dibis (oxy) diethanol and tert-butyl acrylate are prepared by one-step reaction, or by triethylene glycol monobenzyl ether and tert-butyl acrylate by two-step reaction.
preparation	adding tert-butyl acrylate (1g,7.8mmol, 1.0equiv) and benzyl trimethylammonium hydroxide (TritonB)(121mg,0.29mmol,1.0equiv,40% aqueous solution) to acetonitrile solution of diethylene glycol (5.9g,39mmol,5.0equiv), stir at room temperature for 48h,KMnO4 color to determine whether the reaction is complete, remove the solvent on a rotary evaporator, and purify the target product 12-hydroxy -4,7,10-tert-butyl trioxacate 1.6632g, oily liquid with 77% yield by silica gel column chromatography (V (petroleum ether):V (ethyl acetate) = 2:1).
biological activity	Hydroxy-PEG2-(CH2)2-Boc is an ADC linker for the synthesis of antibody-coupled drugs (ADC), Hydroxy-PEG2-(CH2)2-Boc is derived from the patented WO2004008101A2 (compound 196). Hydroxy-PEG2-(CH2)2-Boc can also be used as PROTAC linker for PROTAC synthesis..
