Associated factors for discussing advance directives with family physicians by noncancer outpatients in Japan
Background:Advance directives (ADs) are seldom discussed between primary care physicians (PCPs) and their patients, especially those with noncancer diseases. The aim was to identify the factors associated with discussing AD by noncancer patients with their physicians.Methods:This cross-sectional study was conducted in a hospital or clinic from October to December 2017. Physicians chose eligible noncancer patients aged 20 years or older to respond to an anonymous self-completed questionnaire inquiring about the objective variable "I want to discuss AD with my doctor," as well as basic characteristics, and facilitators and barriers to discussing AD identified in previous studies. The physicians responded to a survey comprising the Palliative Performance Scale (PPS) and inquiring about the disease category for each patient. Data were analyzed using binomial logistic regression analysis.Results:A total of 270 patients (valid response rate, 79.6%) were included. Multivariate analysis identified a period of visit to the study site ≥ 3 years (odds ratio [OR], 2.07; 95% confidence interval [CI], 1.05-4.10), physicians who are very good at taking care of patients\u27 disease (OR, 12.68; 95% CI, 1.12-143.22), and patients\u27 worry about their quality of life (QOL) in the future (OR, 2.69; 95% CI, 1.30-5.57) as facilitators for discussing AD with physicians, and PPS ≤ 90 (OR, 0.51; 95% CI, 0.26-0.98) as a barrier.Conclusions:Our study indicates that patients\u27 future QOL concerns, a long period of visit to a hospital, and the presence of physical symptoms were associated with the willingness of noncancer patients to discuss AD with PCPs

Efficient Diastereoselective Synthesis of (2R,3R,4R)-2-Amino-3-hydroxy-4,5-dimethylhexanoic Acid, the Lactone Linkage Unit of Homophymine A
Acid-promoted Cascade Cyclization to Produce Fused-polycyclic Indole Derivatives
An acid-promoted novel cascade cyclization is described. Using 8 equiv of trifluoroacetic acid or a catalytic amount of Lewis acid as the promoter, structurally diverse polycyclic cyclopenta[<i>b</i>]indoles were obtained in moderate to excellent yield. This cascade process was extremely effective for the synthesis of 8-membered ring-fused cyclopenta[<i>b</i>]indole derivatives
Construction of Divergent Fused Heterocycles via an Acid-Promoted Intramolecular <i>ipso</i>-Friedel–Crafts Alkylation of Phenol Derivatives
Two
different cascade cyclization processes were developed using aryl
group-substituted propargyl alcohol derivatives with a <i>p</i>-hydroxybenzylamine unit as common substrates. Using TFA as an acid
promoter, an intramolecular <i>ipso</i>-Friedel–Crafts
alkylation of phenol derivatives, formation of an iminium cation via
a rearomatization-promoted C–C bond cleavage, an aza-Prins
reaction, and a 6-membered ring formation proceeded sequentially,
producing a variety of fused-tricyclic dihydroquinoline derivatives
in 45–99% yield. In addition, a one-pot sequential silver acetate-catalyzed
hydroamination/etherification–acid-promoted skeletal rearrangement
was examined using the same series of substrates, affording fused-tricyclic
indole/benzofuran derivatives in 66–89% yield
Synthetic Study of Pactamycin: Enantioselective Construction of the Pactamycin Core with Five Contiguous Stereocenters
A synthetic
study of pactamycin is described. Enantioselective
construction of the aminocyclopentitol core of pactamycin bearing
five contiguous stereocenters was achieved based on an organocatalytic
asymmetric aziridination of 2-cyclopentene-1-one, a regio- and diastereoselective
1,3-dipolar cycloaddition, and a rhodium-catalyzed C–H amination
reaction

Pd-Catalyzed Cascade Cyclization by Intramolecular Heck Insertion of an Allene–Allylic Amination Sequence: Application to the Synthesis of 3,4-Fused Tricyclic Indoles
A novel Pd-catalyzed cascade cyclization
by intramolecular Heck
insertion of an allene–allylic amination sequence was developed.
Allenes tethered to <i>ortho</i>-iodoaniline derivatives
at the <i>meta</i>-position were reacted with 5–10
mol % of Pd catalyst and 4 equiv of K<sub>2</sub>CO<sub>3</sub> in
DMSO at 90 °C, producing 3,4-fused tricyclic 3-alkylidene indoline
derivatives in moderate to excellent yield. The reaction products
were divergently transformed into three types of 3,4-fused tricyclic
indole derivatives, successfully demonstrating the versatile properties
of the reaction products
