摘要:
An efficient method for the synthesis of aminosterol compounds such as squalamine and compound 1436 is described. A method of the invention provides for regioselective sulfonation of a fused ring system. The fused ring system base can be, for example, a steroid ring base. The aminosterol compounds are effective as, among others, antibiotics, antiangiogenic agents and NHE3 inhibitors.
摘要:
A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring base can be, for example, a steroid ring base or a base of a vitamin D analog. The process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-ene-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamine or other useful aminosterol compounds and intermediates for making aminosterol compounds.

An electrical connector assembly comprises a receptacle electrical connector and a plug electrical connector. The receptacle electrical connector includes a first body having a first and a second tongues and a plurality of first terminals, the first terminals located on opposite surfaces of the first tongue and offset relative to each other. The plug electrical connector includes a second body and a third and fourth mating chambers located in the second body; a plurality of third terminals, wherein the third terminals located on upper and lower sides of the third mating chamber are offset relative to each other. The receptacle electrical connector and the plug electrical connector can mate with each other so the first terminals and the third terminals are mated with each other to transmit signals and the second tongue and the fourth mating chamber are connected to transmit power.
