The rearrangement reactions of silylated alcohols bearing the highly strained structures of cyclopropene and cyclopropanol connected in adjacent positions have been studied under ZnI2- and Rh(I)-catalyzed conditions. The results show intriguing
Reaction of cyclic α-hydroxy epoxides with a strong base: A new 1,2-rearrangement, evidence for a carbenoid pathway

Several substituted five- and six-membered cyclic α,β-unsaturated ketones are readily available by treatment of the corresponding α-hydroxy epoxides with an organolithium reagent. The reaction involves a new carbenoid 1,2-alkyl rearrangement. Evidence for the carbenoid intermediate has been obtained by an intramolecular trapping of the highly reactive species.
THE INFLUENCE OF HYDROGEN BONDING ON THE SOLVOLYTIC REACTIVITY OF NICOTINATES IN FLUORINATED ALCOHOLS

A systematic investigation of solvolytic reactivities of allylic and benzylic nicotinates and their N-methylated derivatives in 80percent EtOH, 97percent TFE and 97percent HFIP was undertaken.The nicotinates in 97percent HFIP are slightly more reactive th

In an attempt to study possible ?-participation in allyl derivatives, 2-alkenyl-3-methyl-2-cyclohexenyl p-nitrobenzoates 6 and 7 were solvolyzed in 97 wt percent trifluoroethanol and 80 vol percent ethanol.These esters show in both solvents a solvolysis r
Strategic Synthesis based on Cyclohexadienes: Preparation of 2-, 2,3- and 2,4-Substituted Cyclohexenones; Synthesis of (Z)-Heneicosa-6-en-11-one

The mesomeric anions, generated from 1-methoxycyclohexa-1,4-diene, 1-methoxy-5-methylcyclohexa-1,4-diene, and 1-methoxy-4-methylcyclohexa-1,4-diene with potassium amide in liquid ammonia, have been readily alkylated and the resulting dienes were hydrolysed to yield 2-alkyl-, 2,3-dialkyl- and 2,4-dialkyl-cyclohex-2-enones in good yield.Arylation of the above mesomeric anions followed by hydrolysis afforded 2-arylcyclohex-2-enones in addition to substituted biphenyls.A new and efficient synthesis of the male sex attractant of the Douglas Fir Tussock Moth, (Z)-heneicosa-6-en-11-one is described using the above methodology.
