Synthesis of 3,5-disubstituted-1,2-dioxolanes: access to analogues of mycangimycin and some rearrangement products

Mycangimycin is a eicosa-heptenic acid containing an unprecedented 3,5-disubstituted-1,2-dioxolane ring with promising anti-fungal and antimalarial activity. Most reported methods to prepare 1,2-dioxolanes are targeting 3,3,5,5-tetrasubstituted or 3,3,5-trisubstituted 1,2-dioxolanes. Thus, some methods for synthesizing these unusual 3,5-disubstituted 1,2-dioxolanes were investigated. The most promising approach was the use of a Kulinkovich reaction followed by an oxidative ring opening of the cyclopropanol with Co(acac)2to reach the peroxy-hemiketal structure. Successive triflic acid mediated silane reduction of the corresponding peroxy-hemiketal afforded the expected 3,5-disubstituted-1,2-dioxolane ring. Through our studies, some unprecedented rearrangements of 1,2-dioxolane rings were observed, which will be discussed in this Letter. Finally, two saturated analogues of mycangimycin were synthesized.

N-Heterocyclic carbene-catalyzed oxidations

N-Heterocyclic carbenes catalyze the oxidation of allylic and benzylic alcohols as well as saturated aldehydes to esters with manganese(IV) oxide in excellent yields. A variety of esters can be synthesized, including protected carboxylates. The oxidation proceeds under mild conditions, with low loadings of a simple triazolium salt pre-catalyst in the presence of base. Substrates containing potentially epimerizable centers are oxidized while preserving stereochemical integrity. The acyl triazolium intermediate generated under catalytic conditions can be employed as a chiral acylating agent in the desymmetrization of meso-diols.

N-heterocyclic carbene-catalyzed oxidation of unactivated aldehydes to esters

(Chemical Equation Presented) N-Heterocyclic carbenes catalyze the oxidation of unactivated aldehydes to esters with manganese(IV) oxide in excellent yield. The reaction proceeds through a transient activated alcohol, which when generated in situ allows for the selective oxidation of the aldehyde under mild conditions. These conditions successfully oxidize potentially epimerizable aldehydes and alcohols while preserving stereochemical integrity. A variety of ester derivatives can be synthesized with variation of the acylated alcohol as well as the unactivated aldehyde.

Tandem reduction-olefination of triethyl 2-acyl-2-fluoro-2-phosphonoacetates and a synthetic approach to Cbz-Gly-Ψ[(Z)-CF{double bond, long}C]-Gly dipeptide isostere
