Enantioselective Tandem Oxidation/Michael–Aldol Approaches to Tetrasubstituted Cyclohexanes

Enantioselective tandem Michael–aldol and oxidative Michael–aldol approaches have been achieved for the formation of diversely substituted cyclohexanes in total regio-, diastereo- and enantioselective fashion. The presence of nitro, hydroxy and keto groups in the product provides a wide scope for further structural transformations. Furthermore, the utility of the catalytic process is demonstrated in the context of enantioselective formal synthesis of ABT-341, a DPP4 inhibitor.

Asymmetric domino nitro-michael/horner-wadsworth-emmons reaction for disubstituted cyclohexenecarboxylate annulation: Efficient synthesis of dipeptidyl peptidase IV inhibitor ABT-341 and influenza neuraminidase inhibitor

An asymmetric domino nitro-Michael/Horner-Wadsworth-Emmons (HWE) reaction involving α,β-unsaturated aldehydes and nitro phosphonates has been developed, which gave 4,5-disubstituted cyclohexenecarboxylates with high stereoselectivities (dr up to >20:1, ee

One-pot reactions accelerate the synthesis of active pharmaceutical ingredients

All in one: A one-pot synthesis of the dipeptidylpeptidase IV selective inhibitor ABT-341 (see structure) by using an "uninterrupted sequence of reactions" has been developed. This strategy broadens the spectrum of one-pot reactions and is poised to speed up the synthesis of medicinally relevant drug compounds. (Figure Presented)

One-pot high-yielding synthesis of the DPP4-selective inhibitor ABT-341 by a four-component coupling mediated by a diphenylprolinol silyl ether

A dream come true: ABT-341 was synthesized in high yield with excellent diastereo- and enantioselectivity in a one-pot process mediated by a diphenylprolinol silyl ether (see scheme; TMS=trimethylsilyl). Thus, an asymmetric Michael reaction, a domino Mich
