Abstract:Notes (0.35 mm) [lit.9 73°,(2.0 mm), 37% yield by Na reduction],Trans Esters. The trans esters in Table I were all prepd in the usual manner by addn of the acid chloride in PhH to the alcohol and Et3N in PhH. Nmr (CDC13) spectra of all trans esters were similar to that of the alcohol. Under triple irradiation, decoupling both CH2 groups, the vinyl protons of the morpholino pivalate appeared as a singlet (half-bandwidth 3 Hz).4-Amino-2-butyn-l-ol Esters. The esters in Table II were prepd as above for the trans… Show more
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.
