Novel photolabile protecting group for carbonyl compounds.
[reaction: see text] A novel type of photo-protecting group for carbonyl compounds is described. The protecting group is readily accessed in one step from commercially available material. Installation of the protecting group upon the carbonyl compounds is achieved in excellent yields. The carbonyl compounds in their protected form are remarkably stable under various conditions and can be releas...
متن کاملNovel Amino Protecting Group Chemistry
Functional group incompatibility in the synthesis of complex organic molecules has been a problem since the infancy of organic chemistry. Emil Fischer made a valuable contribution to organic chemistry when he came up with the notion that an otherwise reactive functional group could be temporarily rendered inert by attaching a suitable protecting group that could then later be removed [1]. Today...
متن کاملA Novel Methodology for Structural Matrix Identification using Wavelet Transform Optimized by Genetic Algorithm
With the development of the technology and increase of human dependency on structures, healthy structures play an important role in people lives and communications. Hence, structural health monitoring has been attracted strongly in recent decades. Improvement of measuring instruments made signal processing as a powerful tool in structural heath monitoring. Wavelet transform invention causes a g...
متن کامل2-Benzamidoethyl group--a novel type of phosphate protecting group for oligonucleotide synthesis.
A number of 5'-O-(4,4'-dimethoxytrityl)thymidine N,N-diisopropylamino phosphoramidites protected at P(III) with derivatives of 2-benzamidoethanol were synthesized and incorporated into synthetic oligonucleotides. Depending on substitution patterns at the alkyl chain, amido group, and phenyl ring, the time required for removal of these protecting groups using concentrated ammonium hydroxide vari...
متن کاملThe total syntheses of basiliolide C, epi-basiliolide C, and protecting-group-free total syntheses of transtaganolides C and D.
The total syntheses of basiliolide C and previously unreported epi-basiliolide C are achieved by an Ireland-Claisen/Diels-Alder cascade. The development of a palladium catalyzed cross-coupling of methoxy alkynyl zinc reagents allows for the protecting-group-free syntheses of transtaganolides C and D. Syntheses of transtaganolides C and D are accomplished in a single operation to generate three ...
