was determined in the gas-phase in opening reactions with MeOH, using a gaseous acid (D3+, CnH5+, Me2F+) as the promoting agent. The results obtained indicate the incursion in the opening process in the gasphase of H+(or D+)-mediated chelated bidentate species completely absent in the corresponding reactions (methanolysis) carried out in the condensedphase.
使用气态酸(D 3 +,C n H 5 +,Me 2 F +)作为促进剂,在与MeOH进行开环反应的气相中,确定了具有远距离O-官能度的环己烯氧化物的区域化学行为。所获得的结果表明,在缩合相中进行的相应反应(甲烷分解)中完全不存在H +(或D +)介导的螯合双齿物质在气相中的打开过程。

A genus of arylsulfonamide derivatives of aminocycloalkanols is disclosed. The compounds are of the following genus (I):. The compounds induce FOXO1 transcription factor translocation to the nucleus by modulating PP2A and, as a consequence, exhibit anti-proliferative effects. They are useful in the treatment of a variety of disorders, including as a monotherapy in cancer treatment, or used in combination with other drugs to restore sensitivity to chemotherapy where resistance has developed.
