Reaction betweenβ-ethylenic bromides CH2CHCH(R)CH22Br and magnesium in ether has been studied. With R = CHCH2, it gives rise both to normal and rearranged Grignard reagents. With R = C2H5 and C6H5, only the normal Grignard reagent is formed.
反应betweenβ烯溴化物CH 2 CHCH(R)CH 2 2BR和在乙醚中的镁进行了研究。当R = CH = CH 2时,它会同时产生正常和重排的格氏试剂。当R = C 2 H 5和C 6 H 5时,仅形成普通的格氏试剂。

The present invention relates to certain compounds and to methods for the preparation of certain compounds that can be used in the fields of chemistry and medicine. Specifically, described herein are methods for the preparation of various compounds and intermediates, and the compounds and intermediates themselves. More specifically, described herein are methods for synthesizing Salinosporamide A and its analogs from a compound of formula (V).
The present invention encompasses the surprising finding that nanoparticle compositions can have beneficial effects on allergy even when prepared without a known specific allergy therapeutic. The present invention provides such nanoparticle compositions. In some embodiments, provided nanoparticles are associated with functional elements that cause the nanoparticles to mimic bacterial cells. The present invention encompasses the surprising finding that provided nanoparticles may be useful for treatment and/or prevention of multiple different allergies in a single patient. The present invention encompasses the recognition that provided empty nanoparticles may be useful as a “pan-allergy” therapeutic and/or vaccine.
