Asymmetric Intramolecular Ene Reaction Catalyzed by a Chiral Titanium Reagent and Synthesis of (-)-epsilon-Cadinene

A highly diastereo- and enantio-selective intramolecular ene reaction was developed by employing a chiral titanium reagent generated in situ from TiCl2(OPri)2 and a tartrate-derived chiral 1,4-diol.This reaction afforded masked cyclohexanone and cyclopentanone derivatives with high optical purities which were synthetically useful chiral building blocks.From the intramolecular ene product (-)-epsilon-cadinene was synthesized by the use of the newly developed intramolecular Michael reaction.

Efficient chiral monophosphorus ligands for asymmetric Suzuki-Miyaura coupling reactions

A series of novel P-chiral monophosphorus ligands exhibit efficiency in asymmetric Suzuki-Miyaura coupling reactions, enabling the construction of an array of chiral biaryl products in high yields and excellent enantioselectivities (up to 96% ee) under mild conditions. The carbonyl-benzooxazolidinone moiety in these chiral biaryl products allows facile derivatization for further synthetic applications. A computational study has revealed that a pi-pi interaction between the two coupling partners can enhance the enantioselectivity of the coupling reaction.

1,3-Dipolar cycloaddition of N-substituted dipolarophiles and nitrones: Highly efficient solvent-free reaction

(Chemical Equation Presented) New isoxazolidines were synthesized in good to excellent yields by 1,3-dipolar cycloaddition of N-vinylamide dipolarophiles and nitrones. Strikingly, solvent-free conditions gave high conversion and yields, shortened reaction time, and minimized degradation products. N-Vinyloxazolidin-2-one and its analogues used in these cycloaddition reactions were conveniently prepared in excellent yields by a modified version of Buchwald’s one-step copper-catalyzed vinylation using vinyl bromide. From the adducts, a two-step access to various unsymmetric aspartate derivatives was also described.

Several new methods for the synthesis of differently substituted 2-amidofurans are described. The thermolysis of furan-2-carbonyl azide results in a Curtius rearrangement and the resulting furanyl isocyanate was trapped with various organometallic reagents. A second method consists of a C-N cross-coupling reaction of a bromo-substituted furan with various amides, carbamates, and lactams. The CuI-catalyzed cross-coupling reaction between furanyl bromides and amides furnished 2- and 3-substituted amidofurans in 45-95% yield. The third protocol used involves the reaction of cyclic carbinol amides with triflic anhydride. The reaction proceeds under very mild conditions to provide alpha-(trifluoromethyl)sulfonamido-substituted furans in high yield. The resulting iminium ion derived from the reaction of the hydroxy pyrrolidinone with Tf2O undergoes a facile ring opening as a consequence of the adjacent hydroxyl group to produce an imino triflate intermediate. Subsequent cyclization of this highly electrophilic imine with the oxygen atom of the adjacent carbonyl group leads to an imino dihydrofuran that reacts further with another equivalent of Tf2O to give the observed product.

2-Oxazolidinones are synthesized in high yield by oxidative carbonylation of beta-amino alcohols using salen-Co(II)/NaI or salen-Co(III)-I as a catalyst and using CO as the carbonyl source. Studies of functional group compatibility using a series of substituted salen-Co(II) or salen-Co(III)-I complexes demonstrate a broad tolerance of functionality during the carbonylation reaction.
