Convenient synthesis of 1,3,6-triene systems through alkylation of 3-methyl-3-sulfolene

Various 1,3,6-triene systems have been synthesised through alkylation of 3-methyl-3-sulfolene with conjugated aldehydes followed by silylation and subsequent desulfonylation. A new route to synthesis of (+/-)-α-chamigrene, isofokienol and 5-hydroxy-α-farn

Ionic Photodissociation of Polyenes via a Highly Polarized Singlet Excited State

Several polyene acetates and polyene methyl ether were prepared.Upon direct excitation these polyenes undergo ionic photodissociation from their singlet excited states.Triplet-sensitization experiments on these polyenes revealed that the ionic photodissociation process is restricted to singlet excited states.The rationale put forward is that the polyene chromophore undergoes charge separation/polarization in the singlet excited state, which leads to ionic photodissociation.

A novel regioselective synthesis of allylsilanes

The anions derived from allyl sulfones were silylated in the α-position. Reductive desulfonylation gave the desired allylsilanes regioselectively
