Expanding the medicinal chemistry toolbox: stereospecific generation of methyl group-containing propylene linkers

Use of alkyl substituted propylene linkers as a strategy for fine-tuning the biological activity of medicinal agents requires ready access to these substrates. Herein, a general strategy is described for stereospecifically generating 18 chiral mono- and di-methylpropylene linkers. All twelve vicinal 1,2-propylene targets were generated from methyl-3-hydroxybutanoate and all 1,3-disubstituted targets from pentane-2,4-diol.

Stereoselective Aldol-Type Cyclization Reaction Mediated by Dibutylboron Triflate/Diisopropylethylamine

(Equation presented) Dibutylboron triflate/diisopropylethylamine mediated aldol-type cyclization provides an expedient route for the stereoselective synthesis of cyclic ethers in a single step. The method is highly efficient for the stereoselective synthesis of 4-cis-tetrahydropyranones. The reaction is proposed to proceed via an SN1-type mechanism through a chair-like transition state, in which both substituents occupy equatorial positions.

A homogeneous catalyst for reduction of optically active esters to the corresponding chiral alcohols without loss of optical purities

A ruthenium complex was found to catalyze the hydrogen reduction of esters under mild and neutral conditions. A variety of optically active esters can be reduced to the corresponding alcohols in excellent yield without loss of their optical purity or causing undesirable side reactions. Hydrogen reduction needs such simple operations – reaction, concentration, and purification – that the violent quench step and extraction step, which accompany conventional sodium borohydride or lithium aluminum hydride reduction, can be omitted.

Asymmetric, catalytic, and direct self-aldol reaction of acetaldehyde catalyzed by diarylprolinol

(Chemical Equation Presented) An asymmetric, catalytic, and direct self-aldol reaction of acetaldehyde was catalyzed by diarylprolinol in NMP, affording the trimer acetal, which was generated by the reaction of the self-aldol product with another acetaldehyde molecule in a moderate yield with good enantioselectivity. Acetal is the synthetic equivalent of the self-aldol product, which can be converted into other synthetically useful compounds in one pot without compromising the enantioselectivity.

Iodine-Promoted Rapid Construction of Carbamoylphosphonates from Phosphinecarboxamides

Organic phosphonates and their derivatives are an important class of compounds in a variety of fields, especially medicinal chemistry, materials chemistry, agrochemistry and catalysis. For example, phosphonate esters and carbamoylphosphonates are matrix metalloproteinase (MMP) inhibitors, antimetastatic agents and antitumor agents. Phosphonate esters are usually prepared via a multistep transformation from a phenol and an organohalide and require toxic phosphorus halides and aryl/alkyl halides., Palladium-catalyzed couplings of an aryl halide (ArX) with a P?H compound, which were developed by Hirao and co-workers, are now typically used as efficient and substrate-tolerant methods for preparing phosphonates (Scheme 1)., Recently, great advances were made in the synthesis of phosphonate esters via metal-catalyzed C?P bonds couplings of H-phosphonates with C?X compounds (X=B, N, O, S and Si). Despite these clear advances, metal-catalyzed coupling reactions of P?H with C?X(H) are still limited by the need for costly noble metal catalysts. (Figure presented.).
