When 1-chloro-oox(Compound I) is treated with sodium methoxide in methanol, elimination readily occurs to give 1,2-x0oxd compound I). However, the two diastereomers of i (la and lb) each give one single isomer of il (either lla or lib) as shown below. Provide structures for la and ib as well as a mechanistic explanation for the stereopecificity....
