The ozonation of four bornene derivatives, prepared from (R)-(+)-pulegone, which possess a particularly hindered double bond, led to the formation of unexpected products depending on the nature of the solvent. The formation of the corresponding epoxides, ketones with the same skeleton, various lactones and even an allyl alcohol and an allyl chloride (allylic functionalisation) was observed. In two
Treatment of 1-allyl-2-alkenylidenecyclohexanols in acetic acid by the Pd(0) complex [Pd(Ph3P)4] led to 8-methyl bicyclo[4.3.0]nona-1(6),7-dienes. In contrast, only few examples of cyclization vs elimination were observed in acyclic 1,5-hexadien-3-ols.
