Zn(II)- or Rh(I)-catalyzed rearrangement of silylated [1,1'-Bi(cyclopropan) ]-2'-en-1-ols

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

A novel tandem [2 + 2] cycloaddition-Dieckmann condensation with ynolate anions. Efficient synthesis of substituted cycloalkenones and naphthalenes via formal [n + 1] cycloaddition

A novel tandem [2 + 2] cycloaddition-Dieckmann condensation via ynolate anions is described. Ynolate anions are useful for the formation of reactive β-lactone enolates via a pathway not involving the enolization of the corresponding β-lactones. The [2 + 2] cycloaddition of ynolate anions with δ- or σ-keto esters, followed by Dieckmann condensation, gives bicyclic β-lactones, which are easily decarboxylated to produce synthetically useful 2,3-disubstituted cyclopentenones and cyclohexenones in one pot. This tandem reaction was applied to a novel, one-pot synthesis of highly substituted naphthalenes.

Photochemical Cyclization of 2-Alkyl-3-aryl-2-cyclohexenones and 2-Alkoxy-3-aryl-2-cyclohexenones

Irradiation at 254 nm of 2-alkyl-3-aryl-2-cyclohexenones and 2-alkoxy-3-aryl-2-cyclohexenones leads to oxidative cyclization involving the aryl group and the 2-alkyl or the 2-alkoxy substituent.This cyclization cannot be sensitized by triplet sensitizers

CYCLISATION PHOTOCHIMIQUE D'ALKYL-2 ARYL-3 CYCLOHEXENE-2 ONES

In methanol, 2-alkyl-3-aryl-2-cyclohexenones undergo an oxidative photocyclization at 254 nm to provide polycyclic compounds with a phenanthrenic skeleton.
