Nanocerium oxide mediated an efficient and green protocol has been described for the chemoselective N-tert-butyloxycarbonylation of amines under the solvent-free conditions at ambient temperature. Various aliphatic, aromatic and heteroaromatic amines were protected using developed protocol and several functional groups such as alcohol, phenol and ester were well tolerated under these conditions. The rapid reaction rate, mild conditions, very good functional group tolerance, excellent yield, solvent-free, easy recovery products and excellent catalyst recyclability are the advantages of this protocol. This makes the protocol feasible, economical and environmentally benign.

Sulfated tungstate catalyzed an efficient and ecofriendly protocol has been described for the chemoselective N-tert-butyloxycarbonylation of amines under the solvent-free conditions at room temperature. The variety of functionalized aliphatic, aromatic and heteroaromatic amines efficiently undergoes the N-tert-butyloxycarbonylation under the developed protocol. The aminoalcohol, aminophenol, aminoester as well as various chiral amines underwent the chemoselective N-Boc protection under the optimized reaction condition. The rapid reaction rate, mild conditions, very good functional group tolerance, excellent yield, solvent-free, easy recovery products and excellent catalyst recyclability are the advantages of this protocol. This makes the protocol feasible, economical and environmentally benign.

, p. 480 - 501 (2019/02/12)
The capsid assembly is an essential step for Hepatitis B Virus (HBV) life cycle and is an important target for anti-HBV drug development. In this report, we identified a hit compound with aminothiazole structure by the high throughput screening (HTS) which inhibited the interaction of HBV capsid protein within the cells. The structure hopping and SAR studies of the hit compound afforded compound 79 with potent anti-HBV replication activity and good basic drug-like properties. The working mechanism studies showed that compound 79 could bind to the similar binding site of known HBV capsid inhibitor with heteroaryldihydropyrimidine (HAP) scaffold, through similar hydrophobic interactions but with a different hydrogen bond. This compound exerted potent inhibitory effect upon HBV production, either in cell culture or in mice with no obvious acute toxicity. We propose that further development of this compound could lead to novel potent anti-HBV inhibitors that target HBV capsid assembly.

A catalyst-free, efficient and green protocol has been developed for the chemoselective N-Boc protection of amines by using glycerol as a solvent at room temperature. A variety of functionalized amines, such as aliphatic, aromatic as well as heteroaromatic were protected using the developed protocol. N-tert-Butyloxycarbonylation derivatives were formed without the formation of isocyanate, urea, N,N-di-t-Boc, or oxazolidinone as side products. The operational simplicity, cleaner reaction, rapid reaction convergence, functional group tolerance, excellent yield, high selectivity, catalyst-free feature and solvent recyclability are the distinct advantages of this protocol. Owing to these merits, this protocol is feasible, economical and environmentally benign.

The invention provides thiazole heterocyclic compounds, and a preparation method and application thereof. The thiazole heterocyclic compounds have a general structural formula as described in the specification. Results of cell-level experiments show that the thiazole heterocyclic compounds provided by the invention can inhibit proliferation of K562, HL60 and KGla cells. In particular, the compound (compound 4c) in an embodiment 3 can also inhibit proliferation of K562, HL60 and KGla cells under the condition that the concentration of the compound is lower than the concentration of a positive control drug dasatinib. Thus, the thiazole heterocyclic compounds provided by the invention can be used for treating leukemia.
