资源简介：
A method
for chemoselective carbonyl ylide formation utilizing
the Rh(II) catalyzed decomposition of electronically differentiated
diazo malonates is disclosed. Treatment of ethyl, trifluoro ethyl
diazo malonate with a Rh(II) catalyst selectively forms a carbonyl
ylide from the relatively electron rich ethyl ester. This carbonyl
ylide can be trapped by various alkynes giving highly functionalized
oxabicyclic compounds in a chemo-, regio-, and diastereoselective
fashion.
