Published: December 2015

New monocyclic phosphate, phosphonate and difluorophosphonate analogs of the natural AChE inhibitor cyclophostin were synthesized and their activity toward human AChE examined. Surprisingly, the phosphate, phosphonate, and difluorophosphonate analogs all showed diminished activity when compared with the natural product.

Three α,α-difluorophosphonate derivatives of fosmidomycin were synthesized from diethyl 1,1-difluorobut-3-enylphosphonate and were evaluated on . Two of them are among the best 1-deoxy-d-xylulose 5-phosphate reductoisomerase inhibitors, with IC in the nM range, much better than fosmidomycin, the reference compound. They also showed an enhanced antimicrobial activity against on Petri dishes in comparison with the corresponding phosphates and the non-fluorinated phosphonate.

Described is an efficient stereocontrolled route into valuable, densely functionalized fluorinated phosphonates that takes advantage of (i) a Clostridial enzyme to set the absolute stereochemistry and (ii) a new [3,3]-sigmatropic rearrangement of the thiono-Claisen variety that is among the fastest sigmatropic rearrangements yet reported. Here, a pronounced rate enhancement is achieved by distal fluorination. This rearrangement is completely stereoretentive, parlaying the enzymatically established β-C-O stereochemistry in the substrate into the δ-C-S stereochemistry in the product.

Copper catalyzed cross-coupling of iodobenzoates with bromozinc-difluorophosphonate.

Org Lett

April 2012

Key Laboratory of Organofluorine Chemistry, Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, 345 Lingling Road, Shanghai 200032, China.

A copper-catalyzed cross-coupling of iodobenzoates with bromozinc-difluorophosphonate, generated from diethyl bromodifluoromethylphosphonate and zinc in dioxane, is reported. The notable features of this reaction are its high reaction efficiency, excellent functional group compatibility, and operational simplicity. This protocol provides a useful and facile access to aryldifluorophosphonates of interest in life science.
