A facile and highly diastereoselective method for the construction of 2-quaternary 1,3-amino alcohols and 1,3-diols has been developed on the basis of the AlEt3/THF-promoted tandem rearrangement/reductive reaction of α-hydroxy (amino) aziridines (ep

Prochiral ketones are reduced to enantioenriched, secondary alcohols using catecholborane and a family of air-stable, bifunctional thiourea-amine organocatalysts. Asymmetric induction is proposed to arise from the in situ complexation between the bor

Using CrCl 2 in THF at room temperature, trichloromethyl carbinols and trichloromethylalkanes are readily transformed to the highly reactive α-chlorocarbenes, carbynes and α-chloro-α-chromium(III) vinylidene carbenoids. A mechanistic study is carr

An efficient synthesis of the C20-C46 segment of phorboxazole B is described. The key steps involved Hg(OAc)(2)/I(2)-induced cyclization to construct the cis-tetrahydropyran moiety, the coupling of the metalated 2-methyloxazole 7 with lactone 6, and

A stereoselective synthesis of C28–C46 segment of phorboxazole B is described. Key features of the synthetic route involved the use of 1,3-asymmetric induction of Mukaiyama aldol reaction to construct the stereogenic center at C35, and the employme

s: THF-inactivated AlEt 3 has been found to have an interesting double reactivity: Lewis acidity and reduction activity, which can result in a novel tandem rearrangement/reduction of α-hydroxy (or amino) heterocyclopropane. On the basis of this obse

A general and efficient approach for synthesis of an isodaucane sesquiterpenes has been developed by use of a novel and key rearrangement of a eudesmane enol ester epoxide. As an example, the 7-epi-14-isocyano-isodauc-5-ene has been successfully synt
