DOI: 10.1002/ejoc.202200255
Abstract: Abstract Fluorination is a potent method to modulate chemical properties of glycans. Here, we study how C3‐ and C6‐fluorination of glucosyl building blocks influence the structure of the intermediate of the glycosylation reaction, the glycosyl… read more here.

DOI: 10.1021/acs.orglett.2c01088
Abstract: B(C6F5)3 was found to catalyze an unusual double reduction of oxetanes by hydrosilane with aryl migration via neighboring group participation. Control experiments suggested that the phenonium ion serves as the key intermediate. Minor modification of… read more here.

DOI: 10.1039/d2ra01070d
Abstract: Spiro-heterocycles containing natural products and synthetic analogues have a broader biomedicinal application due to their rigid 3D conformation and structural implications. In this context, constructing spiro-isoxazoline systems have continued our interest in natural products and… read more here.

DOI: 10.3390/molecules25235513
Abstract: Fluorinated nucleoside analogues have attracted much attention as anticancer and antiviral agents and as probes for enzymatic function. However, the lack of direct synthetic methods, especially for 2′,3′-dideoxy-2′,3′-difluoro nucleosides, hamper their practical utility. In order… read more here.
