Esters 3-8 complement C6 Homo sapiens 113-116 25736157-3 2015 The reaction occurs most likely through an initial intramolecular amino-amide interaction, followed by an N- to O-acyl transfer of the side chain from C-4 to the C-6 position to form an ester intermediate (5), detectable by NMR, and subsequent hydrolysis. Esters 186-191 complement C6 Homo sapiens 162-165 12128171-2 2002 The esters synthesized (1 and 2) link AZT, by a succinyl linker, to the C-3 position of glucose and to C-6 of galactose. Esters 4-10 complement C6 Homo sapiens 103-106 9680411-2 1998 Glycosylation of the derived acceptor with reactive groups only at C-6 with an ortho ester of d-mannose proceeded smoothly in dichloromethane in the presence of trimethylsilyl trifluoromethanesulfonate, and the degree of branching was up to 0.6. Esters 85-90 complement C6 Homo sapiens 67-70 15760187-3 2005 Indolizine 6, containing an ester group at C-6, was reductively alkylated to give dihydroindolizines 8 and 9 possessing a quaternary carbon center in good yield. Esters 28-33 complement C6 Homo sapiens 43-46 24076198-5 2013 The conjugation of GA onto chitosan probably occurred between amine (C-2), hydroxyl groups (C-3 and C-6) of chitosan and carboxyl groups of GA, forming amide and ester linkages, respectively. Esters 162-167 complement C6 Homo sapiens 100-103 22530559-1 2012 Chiral 2-piperidinone compounds with various C-6 substituents were successfully synthesized via a Pd-catalyzed asymmetric 6-endo cyclization of dienamides, which were evidently activated by both N-p-toluenesulfonyl and C-3 ester substituents. Esters 223-228 complement C6 Homo sapiens 45-48 22229781-3 2012 Even more remarkably, in contrast with the C-6 regioselectivity of other reactions of cellulose and its derivatives, this deacylation shows substantial selectivity for the removal of the acyl groups from the esters of the secondary alcohols at C-2 and C-3, affording cellulose-6-O-esters with high regioselectivity by a simple one-step process employing no protective groups.
