We then decided to vary substitution on the aromatic ring. Product 2b bearing a methoxy-substituted arene was obtained in 50% yield. Product 2c arose in 62% yield from bromobenzene substituted cyclopropene 1c. Remarkably, the reaction starting from 1 gram of 1c resulted in 61% yield of 2c. To our delight, aliphatic alcohols also performed well in the reaction. Moreover, the products demonstrated better stability with no losses observed during purification. Products 2d and 2e were obtained in 74% and 79% yield respectively. An acetal group was tolerated as shown in the formation of diene 2f. A Boc-protected amine did not interfere with the reaction, and product 2g was obtained in 42% yield. Moreover, cyclopropenes 1h and 1i, derived from the addition of dimethylcyclopropenyllithium to naturally occurring citronellal and menthone can also be transformed to the corresponding 1,3-dienes 2h and 2i. Substitution at the aliphatic carbon of the cyclopropene can also be varied. Starting from various spirocyclic cyclopropenes, more complex dienes 2j-m were obtained in 46-98% yield. Finally, we could demonstrate that a free alcohol is not necessary for the reaction: TBS-protected dienol 2n was obtained in 77% yield. It is interesting to note, that the yield of the protected alcohol product is even higher, presumably due to a slower decomosition of the product during the reaction and purification.
