Convenient Synthesis of Ethenylcyclopropane and Some 2-Cyclopropylcyclopropane Derivatives [¹]
Publication History

Abstract
Ethenylcyclopropane (5) was prepared from cyclopropyl methyl ketone (1) in four simple, easily scalable steps (bromination, reduction to the bromohydrin, acetylation of the latter, and reductive elimination with Zn/Cu) in an overall yield of 56%. 1-Bromo-2-cyclopropylcyclopropane (7) (approximately 1:1 mixture of cis- and trans-7) was prepared from 5 via the dibromide 6, and from 7 the boronate cis/trans-8 (ratio 1:1) was obtained in 96% yield. Rhodium(II)-catalyzed cyclopropanation of 5 with ethyl diazoacetate gave ethyl 2-cyclopropylcyclopropanecarboxylate (cis/trans-9, ratio 1:1.4) in 80% yield. The latter was also prepared in 79% overall yield by sequential cyclopropanation of buta-1,3-diene with ethyl diazoacetate [under Rh2(OAc)4 catalysis] and diiodomethane/diethylzinc/trifluoroacetic acid. Curtius degradation of 2-cyclopropylcyclopropanecarboxylic acid (obtained by hydrolysis of the ester) gave 2-cyclopropylcyclopropanamine (1:1.2 mixture of cis- and trans-isomers) in 58% yield.

The bromo ketone 2 is extremely lachrymatory, therefore care must be taken in handling it. A one-pot reaction for the bromination and ensuing NaBH4 reduction without isolation of the bromo ketone gave only a poor yield of impure bromohydrin 3.
12A quick search in the REAXYS data file disclosed 64 references for 2-cyclopropylcyclopropane derivatives, many of which are patents and of rather recent vintage.
