DNA sequencing by synthesis (SBS) on a solid surface during polymerase reaction can decipher many sequences in parallel. We report here a DNA sequencing method that is a hybrid between the Sanger dideoxynucleotide terminating reaction and SBS. In this approach, four nucleotides, modified as reversible terminators by capping the 3'-OH with a small reversible… (More)
Pyrosequencing is a method used to sequence DNA by detecting the pyrophosphate (PPi) group that is generated when a nucleotide is incorporated into the growing DNA strand in polymerase reaction. However, this method has an inherent difficulty in accurately deciphering the homopolymeric regions of the DNA templates. We report here the development of a method… (More)
Two series of 2-cyano-3-substituted-pyridinemethylaminoacrylates, namely 12 new (Z)-2-cyano-3-methylthio-3-substituted-pyridinemethaneaminoacrylates and 10 new (Z)-2-cyano-3-alkyl-3-substituted-pyridinemethaneaminoacrylates, were synthesized as herbicidal inhibitors of photosystem II (PSII) electron transport. All of these compounds were confirmed by (1)H… (More)
A convergent and stereoselective synthesis of the C1-C14 stretch of (+)-discodermolide demonstrates the utility of the "asymmetric catalysis approach" to complex polypropionates. The preparation of this complex synthon requires 15 steps in the longest linear sequence and 19 steps total from inexpensive materials.
[reaction: see text] Asymmetric catalysis and chirality transfer by the 2,3-Wittig rearrangement were combined to provide a syn, anti stereotriad-containing olefinic alcohol in five steps from inexpensive starting materials. Development of this compound, a versatile intermediate for polypropionate synthesis, gave known building blocks for discodermolide.
The traditional Sanger method of DNA sequencing, which uses dideoxynucleotides (ddNTPs) to terminate DNA synthesis at each of the four bases, has remained the gold standard in DNA sequencing for years. The recent development of ‘‘sequencing by synthesis’’ (SBS) techniques, which identify each base as the DNA strand is extended, has offered faster and… (More)
