Applicazioni

6-Tertbutyldimethylsilyl-1,2-dihydroglucal (TBS-DHG) was reported by the Morken Lab to be an effective carbohydrate-derived catalyst for enantioselective diboration of alkenes. Related capabilities were observed with the dihydrorhamnal (DHR) catalyst (901237). TBS-DHG has also been used in ruthenium(0)catalyzed transfer hydrogenation cycloadditions.

A new method for the ring expansion of cyclic diols is described. Using improved conditions for the ruthenium(0) catalyzed cycloaddition of cyclic 1,2-diols with 1,3-dienes, fused [n.4.0] bicycles (n = 3-6) are formed, which upon exposure to iodosobenzene diacetate engage

Catalytic enantioselective diboration of alkenes is accomplished with readily available carbohydrate-derived catalysts. Mechanistic experiments suggest the intermediacy of 1,2-bonded diboronates.

Journal of the American Chemical Society, 140(10), 3663-3673 (2018-02-15)
A mechanistic investigation of the carbohydrate/DBU cocatalyzed enantioselective diboration of alkenes is presented. These studies provide an understanding of the origin of stereoselectivity and also reveal a strategy for enhancing reactivity and broadening the substrate scope.
