Total synthesis of cryptopyranmoscatone B1 from 3,4,6-tri-O-acetyl-d-glucal

Synthesis of amidoglucals and glucal esters via carbonylative coupling reactions of 2-iodoglucal using Mo(CO)6 as a CO source

The synthesis of amidoglucals and glucal esters in good to high yields using 2-iodo-3,4,6-tri-O-acetyl-d-glucal as a substrate, Mo(CO)₆ as a carbon monoxide source and PdCl₂ as a catalyst is reported.

First stereoselective total synthesis of brevipolide M

The first stereoselective total synthesis of a cytotoxic brevipolide M, which shares a pyrone framework bearing a tetrahydrofuran moiety and a cinnamate group with the readily available (-)-DET, is described. The key steps involved in the synthesis are the epoxide-opening, Brown's allylation, and the RCM reaction to install an α,β-unsaturated lactone ring and the inversion of the C-6' stereogenic hydroxyl group using the Mitsunobu reaction.

A practical and scalable synthesis of carbohydrate based oxepines

An efficient, seven-step synthesis of carbohydrate based oxepines is reported using per-O-acetyl septanoses as key intermediates. The scope of the synthesis was evaluated by varying both the pyranose starting materials and protecting groups incorporated into the oxepine products. The practicality of the method make it amenable to scale up as demonstrated by the gram-scale synthesis of the d-glucose derived oxepine.

First total synthesis of cryptopyranmoscatone A2 from d-ribose

The first total synthesis of a naturally occurring styryl lactone, cryptopyranmoscatone A2 has been achieved from inexpensive and highly abundant d-ribose.

The first total synthesis of (+)-goniothalesacetate and syntheses of (+)-altholactone, (+)-gonioheptolide A, and (−)-goniofupyrone by an asymmetric acetate aldol approach

First stereoselective total synthesis of (+)-goniothalesacetate and total synthesis of (+)-altholactone, (+)-gonioheptolide A, and (−)-goniofupyrone have been achieved.
