Screening for health literacy, social determinants, and discrimination in health plans.

Objectives: Health inequities are frequently driven by social determinants of health (SDOH) and structural determinants of health. Our pilot sought to test the feasibility of screening for health literacy (HL) and perceived health care discrimination (PHD) through a live telephonic-facilitated survey experience with managed care patients.

Study Design: Cross-sectional study.

Asymmetric Propargylboration of Aldimines and Ketimines with the Borabicyclo[3.3.2]decanes: Novel Entries to Allenyl Carbinamines, Amino Acids, and Their α-Methyl Counterparts.

Available in either enantiomerically pure form through quantitative Grignard procedures from air-stable crystalline complexes (1, 3), the B-γ-TMS propargylic derivatives of the 10-TMS- (2) and 10-phenyl-9-borabicyclo[3.3.2]decanes (4) provide highly selective entries to 2°-allenyl carbinamines (8, 60-85%, 78-99% ee) and their 3° counterparts (13, 62-82%, 95-99% ee) through their additions to aldimines and ketimines, respectively.

Cyclohexenylboration of Aldehydes and Ketones with the Borabicyclo[3.3.2]decanes (BBDs).

Asymmetric hydroboration of 1,3-cyclohexadiene with 4R produces the allylborane 5RR as essentially a single diastereomer (i.e., no observable 5RS), and its addition to representative aldehydes provides 9RS (52-75%) with excellent selectivity (94-99% ee).

Highly functionalized tertiary-carbinols and carbinamines from the asymmetric γ-alkoxyallylboration of ketones and ketimines with the borabicyclodecanes.

The first asymmetric γ-alkoxyallylboration of representative ketones provides β-alkoxy tert-homoallylic alcohols 10 whose diastereoselectivities range from 99% syn (acetophenone) to 99% anti (pinacolone) both with high ee (>95%). This distribution is attributable to the c/t isomerization of the BBD reagents and the greater reactivity of 7 vs 1 and of aromatic vs alkyl ketones. A ketone-based direct synthesis of a fostriecin intermediate and the tert-amine 26 are reported, each with high selectivities.

(E)-2-boryl 1,3-dienes from the 10-TMS-9-BBDs: highly selective reagents for the asymmetric synthesis of anti-α,β-disubstituted β-allenylamines from the allylboration of aldimines.

The asymmetric allylboration of N-H aldimines with optically pure trans-4-substituted-2-boryl-1,3-dienes 6 is described. These organoboranes 6 serve as near-perfect asymmetric allylborating agents for N-H aldimines for the preparation of anti-1,2-disubstituted-3,4-pentadien-1-amines 11 as essentially single diastereomers in enantiomerically pure form (>98% de, ≥98% ee). Enantiomerically pure cis-2,3-disubstitued piperidines 12 and α,β-disubstituted-β-amino acids 17 are readily prepared through the standard protocols.
