COMU is a high efficiency coupling reagent.The superior reactivity of COMU can be observed by comparing the yields of difficult Aib-Aib coupling performed with the different coupling reagents.COMU can be utilized with the same protocols as HBTU and HATU.In applications where racemization is a significant concern, only one equivalent of base can be used because the morpholino group of COMU acts as an internal base Learn more

Boc-Ala(3-I)-OMe was used to prepare 2',6'-dimethyl-L-tyrosine utilizing a microwave-assisted Negishi coupling. 2&prime,6&prime-dimethyl-l-tyrosine is widely use in the development of synthetic opioid ligands.
