โœฆ Synopsis


The osmylation of several 3-substituted cyclopentenes has been studied. A preference for 0~04 addition syn to an allylic CHR2 substituent is observed. By contrast, bulkier substiments of type CMeR, give rise to a striking reversal of selectivity. These results are interpreted in terms of the stereodivergent nature of the two differently reactive envelope conformations.

Recently, allyltrimethylsilane has been shown to be a good reagent for allylation of acyl halides 1 or carbonyl compounds 2 in the presence of Lewis acid. Now we wish to report here a new and convenient route to cyclopentene derivatives using the reactions of 3-trimethylsilylcyclopentene-1, a cyclic
