Product Description

CAS no 51901-85-0 B-BroMocatecholborane

Certain ethers, esters, and anforzide protecting groups are selectively cleaved under mild conditions. The reactivities for the most commonly used protecting groups for this reagent are: 1a) MOMOR, MEMOR> BOC> CBZ, tBuOR> PhCH2OR> CH22OR> tBuO2CR, secondary alkyl OR> PhCH2O2CR, primary alkyl OR >> alkyl O2CR. The reagent B-chlorophenyleneborane reactivity less than 1a (B-bromophenyleneborane), can be used in reactions that require higher selectivity, such as the synthesis of natural products.In addition, TBDMS, TBDPS and PMB ether will not be affected by reagent 1.
