An organocatalytic and highly regio-, diastereo-, and enantioselective intermolecular haloetherification and haloesterification reaction of allyl amides is reported. A variety of alkene substituents and substitution patterns are compatible with this chemistry. Notably, electronically unbiased alkene substrates exhibit exquisite regio- and diastereoselectivity for the title transformation. We also demonstrate that the same catalytic system can be used in both chlorination and bromination reactions of allyl amides with a variety of nucleophiles with little or no modification. A highly regioselective intermolecular haloetherification that proceeds with excellent enantioselectivity, catalyzed by cinchona alkaloid dimers, is reported. The regioselectivity is preserved for unbiased alkyl substituted allyl amides with either E or Z geometry. (DHQD)2PHAL=hydroquinidine 1,4-phthalazinediyl diether.

Dimethylallylguanidine, also known as galegine, isolated from Galega officinalis, has been shown to have weight reducing properties in vivo. Substitution of the guanidine group with an N-cyano group and replacement of guanidine with amidine, pyrimidine, pyridine, or the imidazole moieties removed the weight reducing properties when evaluated in BALB/c mice. However, retention of the guanidine and replacement of the dimethylallyl group by a series of functionalized benzyl substituents was shown to exhibit, and in some cases significantly improve, the weight reducing properties of these molecules in BALB/c, ob/ob, and diet induced obesity (DIO) mice models. The lead compound identified, across all models, was 1-(4-chlorobenzyl)guanidine hemisulfate, which gave an average daily weight difference (% from time-matched controls; ± SEM) of -19.7 ± 1.0, -11.0 ± 0.7, and -7.3 ± 0.8 in BALB/c, ob/ob, and DIO models, respectively.
