For example, the Corey method requires a hydrolytic step with use of mercuric chloride in warm, aqueous a~ etonitrile.~ In some situations, it may become necessary to generate the a,@-unsaturated aldehyde by using even milder conditions. We describe herein a possible solution to this problem. In particular, we show that a new 0- ...
