Changing Trends of Obstetric Hysterectomy Over Last 2 Decades: A Retrospective Analysis from a Single Center Tertiary Care Rural Teaching Hospital of Western India.

Objective: The primary objective of our study to analyze the trend of obstetric hysterectomy (OH) over last 2 decade in rural tertiary care referral center of western India.

Design: Retrospective observational and comparative study from single rural tertiary care referral center of western India.

Method: A retrospective data collected of patients who underwent OH from Jan 2001 to Dec 2021.

Enantioselective total synthesis of (+)-arborescidine C and related tetracyclic indole alkaloids using organocatalysis.

A concise and enantioselective synthesis of the tetracyclic indoles, including the naturally occurring compounds (+)-arborescidine C and (+)-arborescidine B, was achieved by the key step of Pictet-Spengler cyclization reaction with a Jacobsen-type thiourea organocatalyst. The synthetic process was further demonstrated in a pot-economy strategy and was achieved in a one-pot operation.
