We describe a photoinduced copper-catalyzed asymmetric radical decarboxylative alkynylation of bench-stable N-hydroxyphthalimide(NHP)-type esters of racemic alkyl carboxylic acids with terminal alkynes, which provides a flexible platform for the construction of chiral C(sp3)?C(sp) bonds. Critical to the success of this process are not only the use of the copper catalyst as a dual photo- and cross-coupling catalyst but also tuning of the NHP-type esters to inhibit the facile homodimerization of the alkyl radical and terminal alkyne, respectively. Owing to the use of stable and easily available NHP-type esters, the reaction features a broader substrate scope compared with reactions using the alkyl halide counterparts, covering (hetero)benzyl-, allyl-, and aminocarbonyl-substituted carboxylic acid derivatives, and (hetero)aryl and alkyl as well as silyl alkynes, thus providing a vital complementary approach to the previously reported method.

Gaucher disease (GD) results from inherited mutations in the lysosomal enzyme β-glucocerobrosidase (GCase). Currently available treatment options for Type 1 GD are not efficacious for treating neuronopathic Type 2 and 3 GD due to their inability to cross the blood-brain barrier. In an effort to identify small molecules which could be optimized for CNS penetration we identified tamoxifen from a high throughput phenotypic screen on Type 2 GD patient-derived fibroblasts which reversed the disease phenotype. Structure activity studies around this scaffold led to novel molecules that displayed improved potency, efficacy and reduced estrogenic/antiestrogenic activity compared to the original hits. Here we present the design, synthesis and structure activity relationships that led to the lead molecule Compound 31.
