One-Pot Chemoenzymatic Multicomponent Synthesis of Thiazole Derivatives

open access: yesMolecules, 2013
A novel chemoenzymatic one-pot multicomponent synthesis of thiazole derivatives was developed. A series of thiazole derivatives were synthesized with high yields up to 94% under mild enzyme-catalyzed conditions.

Pyrazolo-Thiazoles

open access: yes, 1974
Department of Chemistry, Punjab University, Chandigarh-160014 Manuscript received 11 February 1974; accepted 20 August 1974 Some Pyrazolo(3,4-d)-thiazoles have been synthesised by the condensation of phenyl thioureas with 4-bromo-1,3 diphenyl pyrazolone-5. However, In each case, two products have been isolated.

Structural Basis for the Catalytic Mechanism of ATP‐Dependent Diazotase CmaA6

open access: yesAngewandte Chemie, EarlyView.
Several diazotases have been reported in recent years, but the detailed catalytic mechanism is unclear. From X‐ray crystallography and Cryo‐EM analysis, we obtained the structure of a diazotase CmaA6, which synthesizes 3‐diazocoumaric acid. Kinetic analysis and computational analysis indicated that CmaA6 catalyzes diazotization via an unprecedented ...
