The investigation of Verbesina sphaerocephala afforded an amorphane 7-lactol; the structure was established by interpretation of spectral data and X-ray diffraction analysis.
Regioselectivity in the Reformatsky Reaction of 4-Bromocrotonate. Role of the Catalyst and the Solvent in the Normal vs. Abnormal Modes of Addition to Carbonyl Substrates1 Summary: The regioselectivity of addition of the organozinc reagent derived from ethyl 4-bromocrotonate to 10 carbonyl substrates was found to be dependent on the polarity of solvents and the hardness of metal catalysts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
