Selective hydroxylation of diamantane with 2,3,4,5,6-pentafluoroperbenzoic acid in the presence of molibdenum complexes
摘要:
Oxidation of diamantane with 2,3,4,5,6-pentafluoroperbenzoic acid catalyzed with complexes MoO(O-2)center dot 2QOH, MoO(O-2)(H2O)(2) proceeds selectively affording diamantan-1-ol and diamantan-1-yl 2,3,4,5,6-pentafluorobenzoate.

Methods for synthesis of
1
-(acyloxy)-alkyl carbamates, particularly, the synthesis of
1
-(acyloxy)-alkyl carbamate prodrugs of primary or secondary amine-containing drugs are described. Also described are methods for synthesis of
1
-(acyloxy)-alkyl N-hydroxysuccinimidyl carbonates which are useful intermediates in the synthesis of
1
-(acyloxy)-alkyl carbamates are also described.
Disclosed herein are methods for synthesizing 1-(acyloxy)-alkyl prodrug derivatives of drugs through oxidation of 1-acyl-alkyl derivatives of drugs under anhydrous reaction conditions. The methods typically proceed stereospecifically, in high yield, do not require the use of activated intermediates and/or toxic compounds and are readily amenable to scale-up.
