I have spent a significant part of my life attempting to make cyclopropanes and fancy myself rather knowledgeable in this particular area so you can imagine my surprise when Professor Andy Phillips from University of Colorado mentioned the Kulinkovich cyclopropanation out of the blue (talk entitled: "New Reactions and Strategies for the Synthesis of Complex Natural Products"). I have to admit that I was a full-on Kulinkovich virgin. It's a pretty funky reaction producing 1,1,2-trisubstituted hydroxy-cyclopropanes. These are generally not easy to make so I'm surprised I hadn't seen this stuff before. I'm not sure if anyone has attempted to make an asymmetric version of the reaction but in any event using optically active starting materials Professor Phillips Group managed to make optically active stuff (see below).
I didn't get the yield or dr and I don't know if the stuff has been published yet. However, there's a nice entry in Organic Syntheses (OS) on the Kulinkovich cyclopropanation giving two examples (71 and 80% yield to give one diastereoisomer) as well as some background and the mechanism (see mechanistic explanation from OS below).
