Regioselective Semihydrogenation of Dienes

The Journal of Organic Chemistry, 2011
A one-pot, three-step strategy for the regioselective semihydrogenation of dienes is described. This procedure uses 9-BBN-H as a temporary protective group for alkenes. Yields range from 55% to 95%, and the reaction is tolerant of a variety of common functional groups.

Regioselectivity

2012
This chapter explores regioselectivity. Chemoselectivity means that there are two separate functional groups and that a reagent must choose between them. By contrast, regioselectivity implies that there is one functional group that can react in two different places and a reagent must choose where to react.

Regioselective Allylzincation of Alkenylboronate

Organic Letters, 2001
[reaction: see text] Boryl substitution on an olefin activates the olefinic double bond toward addition of an organozinc reagent. Addition of an allylic zinc reagent to an alkenylboronate thus takes place smoothly to afford a variety of gem-zincio/boryl species.

Selectivity II: Regioselectivity

2022
This chapter focuses on regioselectivity. When devising a synthetic route to an organic molecule, substituents and functional groups must be placed in the required positions, i.e. with the correct regiochemistry. The chapter begins by evaluating the regioselectivity of some of the most common methods for the preparation of alkenes.

Regioselective Hydrodebromination of Polybrominated Indoles

European Journal of Organic Chemistry, 2014
AbstractThe mixture of sodium borohydride and N,N,N′,N′‐tetramethylethylenediamine in combination with a palladium catalyst is a mild and efficient system for the regioselective hydrodebromination of polybrominated indoles with both N‐donating and N‐withdrawing substituents [N‐methyl‐ and N‐(methoxycarbonyl)indoles, respectively].
