Cyclopropenes diene synthesis with

Cyclopropenes cycloaddition-ring opening with - 32, 630 diene synthesis with -30, 469s31... [Pg.246]

A new synthesis of 1,4-dienes involves treatment of aa -dihydroxy-derivatives (455) of cyclopropenes with diphosphorus tetraiodide in the presence of pyridine in benzene. ... [Pg.97]

ROM-CM Sequence The ROM reaction of a cycloalkene engaged in the subsequent CM reaction with an olefinic partner provides the straightforward procedure for the synthesis of diene products having the isolated double bonds. This sequence is applicable not only to relatively strained cycloalkenes but also to unstrained compounds such as cyclohexene. The ROM-CM sequence of norbor-nene compounds or cyclopropene ketals with various olefins is reported for the preparations of natural products. [Pg.700]
