Titanium(IV) Isopropoxide-Catalyzed Formation of 1-Substituted Cyclopropanols in the Reaction of Ethylmagnesium Bromide with Methyl Alkanecarboxylates.
Synthesis 1991; 234
Key words
cyclopropanols - titanium catalysis - Kulinkovich reaction
Significance
The Kulinkovich reaction generates cyclopropanols from simple Grignard reagents and esters in the presence of a titanium(IV) alkoxide catalyst. This reaction has been subsequently expanded to a wide range of substrates (see Review below) and an asymmetric version was also demonstrated by the group of Corey (J. Am. Chem. Soc.
1994, 116, 9345).

Comment
Although the group of Kulinkovich previously reported the synthesis of cyclopropanols through a titanium(IV) alkoxide mediated reaction (Zh. Org. Khim. 1989, 25, 2244), the current report demonstrated a method that was catalytic in titanium.
