New radical reactions of S-alkoxycarbonyl xanthates. Total synthesis of (±)-cinnamolide and (±)-methylenolactocin

Irradiation with visible light of S-alkoxycarbonyl xanthates derived from various alcohols gives rise to alkoxycarbonyl radicals with bifurcate reactivity: loss of carbon dioxide leads to deoxygenated derivatives (i.e. alkyl xanthates) whereas intramolecular addition to a suitably located double bond produces lactones; these new reactions were applied to the total synthesis of (±)-cinnamolide and (±)-methylenolactocin.

Radical-initiated Reduction of Chloroformates to Alkanes by Tri-n-propylsilane. A Method for Removal of Unwanted Hydroxy-Groups from Organic Molecules

Chloroformates of primary and secondary alcohols, produced by the reaction of the alcohol with phosgene, are reduced to the corresponding alkane in excellent yields by reaction with tri-n-propylsilane in the presence of t-butyl peroxide at 140 deg C.Unusually large amounts of initiator are required tO)2 per mol of RO*CO*Cl>.The results are rationalized in terms of a free-radical reaction scheme.
