Reaction of 2H-1-Benzothiete with Diazo Compounds in the Presence of Rhodium(II) Acetate

2,3-Dihydrobenzothiophenes (7a-e) were prepared by the Rh2+ catalyzed reaction of 2H-1-benzothiete (1) and diazo compounds (3a-e). α, β-Unsaturated diazo esters (3b,e) and diazo ketones (3d,e) yielded additionally 4,5-dihydro-1-benzothiepins

Heterocyclic compound for treating osteoporosis as well as preparation method and application of heterocyclic compound

The invention relates to the field of a medicine for preventing and treating osteoporosis. The invention provides a pyrazole heterocyclic compound or pharmaceutically acceptable salt of the compound. An in-vivo test finds out that the pyrazole heterocyclic compound can be used for inhibiting bone turnover rate enhancement and bone destruction, which are caused by ovariectomy; meanwhile, the concentration of blood calcium can be improved and deposition of bones is facilitated, so that the pyrazole heterocyclic compound has remarkable effects of preventing and treating the osteoporosis.

Cu(ii)-catalyzed esterification reaction via aerobic oxidative cleavage of C(CO)-C(alkyl) bonds

A novel Cu(ii)-catalyzed aerobic oxidative esterification of simple ketones for the synthesis of esters has been developed with wide functional group tolerance. This process is assumed to go through a tandem sequence consisting of α-oxygenation/esterification/nucleophilic addition/C-C bond cleavage and carbon dioxide is released as the only byproduct.

A family of low molecular-weight, organic catalysts for reductive C-C bond formation

Hydrazines form a new family of low molecular-weight reducing agents for diazonium salts. Using only small amounts of hydrazine catalyst, the coupling of diazonium salts to a variety of reactive partners has been achieved, without the requirement for either metal adjuvants or irradiation with visible or ultraviolet light. The generality of the concept proposed herein as well as its advantages in the preparative scale is outlined and discussed.
