日期:2008.1.1
The totalsynthesis of racemic merrilactone A (a neurotrophic agent) is described, featuring simultaneous and stereospecific creation of the C4 and C5 stereocenters via a notable silyloxyfuran Nazarov cyclization. Full details of the successful synthetic strategy are given, as well as several examples of the interesting reactivity of intermediates that were prepared and studied during the execution

The reaction of acylpolysilanes with TMSOT and TMS(NTf2) proceed via a series of 1,2 silyl and silyoxy shifts to afford the silanol products 5 and 6 respectively. A unified mechanistic pathway involving the formation of transient silenium ion complexes and silenes which rationalises these products is proposed. The structural assignment of the products is supported by X-ray structures for the phenyl 6a and trifluoromethylphenyl 6b substituted silanols.
