(steroidal), and sugar moieties in their molecules has been synthesized and assayed as inhibitors of the zincenzymecarbonicanhydrase (CA), and more precisely of the cytosolic isozymesCAI andII, and the transmembrane, tumor-associated isozymesCA IX. Some of these compounds were previously reported to act as inhibitors of steroid sulfatases, among which estrone sulfatase (ES) and dehydroepiandrosterone
The combination of a tailored sulfamate with a C4-symmetrical rhodium(II) tetracarboxylate allows to uncover a selective intermolecularamination of unactivated homobenzylic C(sp3)–H bonds. The reaction has a broad scope (>30 examples) and proceeds with a high level of regioselectivity with homobenzylic/benzylic ratio of up to 35:1, thereby providing a direct access to β-arylethylamines that are of

A series of fluorinated-phenylsulfamates have been prepared by sulfamoylation of the corresponding phenols and the inhibition of four physiologically relevant carbonic anhydrase (CA, EC 4.2.1.1) isozymes, the cytosolic CA I and II (off-targets), and the transmembrane, tumor-associated CA IX and XII is investigated. Unlike the lead molecule (phenylsulfamate), a very potent CA I and II inhibitor and a modest CA IX/XII inhibitor, the fluorinated sulfamates were stronger inhibitors of CA IX (K(I)s of 2.8-47 nM) and CA XII (K(I)s of 1.9-35 nM) than of CA I (K(I)s of 53-415 nM) and CA II (K(I)s of 20-113 nM). Some of these compounds were selective CA IX over CA II inhibitors, with selectivity ratios in the range of 11.4-12.1, making them interesting candidates for targeting hypoxic tumors overexpressing CA IX and/or XII.

alcohol sulfamoylation that deploys electron-deficient aryl sulfamates as activated group transfer reagents. The reaction utilizes the simple organic base N-methylimidazole, proceeds under mild conditions, and provides intrinsic selectivity for 1° over 2° alcohols (up to >40:1 for certain nucleosides). The requisite aryl sulfamate donors are stable crystalline solids that can be readily prepared on

Methods for site-selective sulfamoylation of secondary hydroxyl groups in pyranosides are described. Using a boronic acid catalyst, selective installation of a Boc-protected sulfamoyl group at the equatorial position of cis-diols in manno- and galacto-configured substrates has been achieved. Activation of trans-diol groups in gluco- and galacto-configured substrates is also possible by employing an
