The methods, compositions, and kits of the disclosure provide a novel approach for a whole genome, unbiased DNA analysis method that can be performed on limited amounts of DNA. can be used to analyze DNA to determine its modification status. Aspects of the disclosure relate to a method for amplifying bisulfite-treated deoxyribonucleic acid (DNA) molecules comprising: (a) ligating an adaptor to the DNA molecules, wherein the adaptor comprises a RNA polymerase promoter comprising bisulfite-protected cytosines; (b) treating the ligated DNA molecules with bisulfite; (c) hybridizing the bisulfite-treated DNA molecules with a primer; (d) extending the hybridized primer to make double stranded DNA; and (e) in vitro transcribing the double-stranded DNA to make RNA.

important heterocyclic compounds with a broad range of biological activities. A new procedure toward tri- or tetrasubstituted pyrazoles has been developed, via a one-pot gold catalyzed synthesis from hydrazines with alkynyl aldehydes or ketones. The reaction proceeds through consecutive hydrazone formation, 5-endo-dig cyclization and an aza-Claisen rearrangement resulting in the desired polysubstitued pyrazoles
