Journal ArticleDOI
Contribution of Organofluorine Compounds to Pharmaceuticals.
TL;DR: This mini-review analyzes the prevalence of fluoro-pharmaceuticals in the market and categorizes them into several groups based on the chemotype of thefluoro-functional groups, their therapeutic purpose, and the presence of heterocycles and/or chirality to highlight the structural motifs, patterns, and promising trends in fluorine-based drug design.
Journal ArticleDOI
Stereoselective Synthesis of β-Lactam-triflones under Catalyst-Free Conditions.
TL;DR: The first example of the synthesis of β-lactam-triflones is described, where a successive Wolff rearrangement and Staudinger [2 + 2] cycloaddition reaction are key elements for the success of this transformation.
Journal ArticleDOI

TL;DR: The first stereodivergent direct nucleophilic trifluoromethylation of N-sulfinylimines using the potent greenhouse gas "HFC-23, fluoroform" with an organic-superbase or an organometallic-base in high yields and selectivity is demonstrated.
Journal ArticleDOI
Synthesis of CD-ring structure of cortistatin A, an anti-angiogenic steroidal alkaloid from marine sponge
TL;DR: In this paper, the CD-ring structure of cortistatin A (1), a novel anti-angiogenic steroidal alkaloid from Indonesian marine sponge, was achieved by 1,3-chiral transfer method using Johnson-Claisen rearrangement of the chiral allylic alcohol.
Journal ArticleDOI
Stereoselective synthesis of core structure of cortistatin A.
TL;DR: A stereoselective synthesis of the core structure of cortistatin A (1), a novel antiangiogenic steroidal alkaloid from Indonesian marine sponge, is described.
