Aliphatic Nitrile Template Enabled -C-H Olefination of Indene Enoate Esters under Microwave Accelerating Conditions.

Site-selective activation of a particular remote C-H bond in molecules with multiple C-H bonds remains challenging in organic synthesis. In addition, evolving such transformations via the utilization of unconventional techniques is highly desirable. We demonstrated hitherto unexplored double bond geometry-guided and end-on nitrile-template-assisted -C-H functionalization of indene enoate esters under microwave-accelerated conditions.

Access to distal -C-H functionalization of arylmethanesulfonic acid derivatives.

Herein, we report the -C-H olefination of arylmethanesulfonates aided by a potentially versatile aliphatic nitrile-directing group under microwave irradiation conditions with fair to very good yields and good to outstanding regioselectivities. Significantly, the protocol showed broad substrate scope including olefin-derived drugs and cyclic olefins. Remarkably, a dual -C-H bond was amenable to generating the bis-olefination products.

Functionalization of arylacetic acids directing-group-assisted remote -C-H activation.

Herein, we report the first microwave-assisted remote-C-H functionalization aided by a simple nitrile directing template. Notably, the present protocol showed a broad substrate scope enabling -C-H arylation, acetoxylation, and cyanation. Significantly, the microwave-accelerated -C-H functionalization was effective with short reaction times without compromising yields and site selectivity.

Deciphering the Nexus Between Oxidative Stress and Spermatogenesis: A Compendious Overview.

Oxidative stress (OS) and reactive oxygen species (ROS) are one of the main reasons for the multifactorial concern - male infertility. ROS are active components of cellular metabolism that are intrinsic to cellular functioning and are present at minimal and unreactive levels in normal cells. They are an integral component of the sperm developmental physiology, capacitation, and function.
