Inherent directing group enabled, Co(III)-catalyzed C-H allylation/ vi-nylation of isoquinolones [PDF]

The site-selective C8-allylation and vinylation of isoquinolones have been accomplished using allyl acetate and vinyl acetate and oxo group of isoquinolone as an inherent directing group in the presence of Co(III) catalysis. A plausible mechanism for the

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Indole as a Directing Group for Nonaromatic C–H Activation in Palladium‐Catalyzed Cross‐Dehydrogenative Coupling With β‐Ketoesters

ChemistryEurope
The selective activation of aliphatic C–H bonds remains a fundamental challenge in synthetic chemistry. Here we disclose a palladium‐catalyzed cross‐dehydrogenative coupling (CDC) that joins the α‐carbon of β‐ketoesters with the C3‐benzylic position of ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Gesture commands for controlling high-level UAV behavior

SN Applied Sciences, 2021
Directing groups of unmanned air vehicles (UAVs) is a task that typically requires the full attention of several operators. This can be prohibitive in situations where an operator must pay attention to their surroundings.

The Subgroups of Direct Products of Surface Groups

Geometriae Dedicata, 2002
A surface group is the fundamental group of a connected 2-manifold; such a group is either free (of finite or countably infinite rank) or isomorphic to the fundamental group of a closed 2-manifold. Generalizing results for subgroups of direct products of free groups (in particular of \textit{G. Baumslag} and \textit{J. E. Roseblade} [J. Lond. Math. Soc.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
