摘要

12, X= C1; Y= H diazomethane to unsaturated oxazolones is well-known'and since the requisite chloro compound 2 had been reported, 2 we prepared and studied its reaction with diazomethane. The configuration of 2 as reported in 1946 was unknown, and when the synthetic sequence (Scheme I) was carried out, only one isomer of 2 appeared to be produced, as determined by'H NMR and TLC analyses. However, when 2 was treated with ...
