摘要

Abstract: The quaternary N-allyl bromide salt 5 of allyl~-[2-(5-azaadamantylidene)] benzyl ether upon warming gave the Claisen rearrangement products 6 is the ratio EIZ= 93: 7. The epoxidation of the N-oxide 8 of 2-methylene-5-azaadamantane 7 with m-CPBA gives rise to the two diastereomeric epoxides 9 in the ratio E1Z= 19: 81. Reaction of the methyl iodide salt of this olefin with bromine in water produces the E-and Z-dibromides 10 in the ratio 74: ...
