A Novel Stereocontrolled Synthesis of 1,2-<i>trans</i> Cyclopropyl Ketones via Suzuki-Type Coupling of Acid Chlorides with Cyclopropylboronic Acids
The palladium-catalyzed cross-coupling reaction of cyclopropylboronic acids with acyl chlorides was achieved by the combination of Ag2O
and K2CO3 as the base. Highly enantiomerically enriched cyclopropyl ketones (ee >90%) were also obtained by the reaction of corresponding
chiral cyclopropylboronic acids
Distribution of average numbers of non-zero IBD sharing per individual in local IBD matrices.
For each color, a total of 3,403 local IBD matrices of sample size N = 487,252 for 1 cM windows were plotted, with density estimates scaled to maximum of 1. The local IBD matrices were constructed from RaPID and hap-IBD IBD segments called with length β₯ 3 cM, 5 cM, 10 cM.</p
Power comparison of FiMAP and GWAS.
(A) Untyped rare causal variants, 1 cM causal window; (B) Untyped rare causal variants, 1 cM neighboring windows; (C) Haplotype effects, 1 cM causal window; (D) Haplotype effects, 1 cM neighboring windows. In each simulation replicate, finite-sample FiMAP with local IBD matrices constructed from RaPID and hap-IBD IBD segments called with length β₯ 3 cM, 5 cM, 10 cM were benchmarked with a GWAS single-variant test. Empirical power was estimated for FiMAP as the proportion of finite-sample p values less than 0.05/3,403 = 1.47 Γ 10β5, and for GWAS as the proportion of any minimum single-variant p values in each 1 cM testing window less than 5 Γ 10β8, over 1,000 simulation replicates.</p
Proportions of power simulation replicates in which both FiMAP and GWAS or only one approach identified the association.

GWAS and finite-sample FiMAP p values from RaPID IBD segments on chromosome 16.
(A) Waist circumference; (B) Hip circumference; (C) Body mass index; (D) Body weight. IBD segments called by RaPID with length β₯ 3 cM were used in the FiMAP analysis. GWAS p values were shown in grey and unconditional FiMAP p values were shown in orange. GWAS p values β25 were truncated at 1 Γ 10β25. For windows with unconditional FiMAP p values β5, conditional p values after adjusting for all tag variants in each conditional set were shown in blue triangles. (TIF)</p
