[Image: see text] Despite numerous advances in spectroscopic methods through the latter part of the 20th century, the unequivocal structure determination of natural products can remain challenging, and inevitably, incorrect structures appear in the l

Substrate-controlled asymmetric total syntheses and structure confirmation of (+)-(3E)- and (-)-(3Z)-chlorofucin [(E)-1 a and (Z)-1 a], and (+)-(3E)- and (-)-(3Z)-bromofucin [(E)-1 b and (Z)-1 b] were accomplished. Our syntheses feature as key steps

The systematic investigation of chiral bidentate auxiliaries has resulted in the discovery of a chiral 2,2-dimethyl-1-(pyridin-2-yl)propan-1-amine-derived directing group that enables stereoselective palladium(II)-catalyzed intramolecular C(sp3)–O

A highly efficient and stereoselective route to potential synthetic intermediates for ocellenyne and related C15 acetogenin natural products with 6,10-syn- and 6,10-anti-2,5-dioxabicyclo[2.2.1]heptane core structures has been developed by means of an

Elatenyne is a small dibrominated natural product first isolated from Laurencia elata. The structure of elatenyne was originally assigned as a pyrano[3,2-b]pyran on the basis of NMR methods. Total synthesis of the originally proposed pyrano[3,2-b]pyr

We report a completely substrate-controlled approach to the asymmetric total synthesis of representative dioxabicyclic bromoallene marine natural products with either a 2,10-dioxabicyclo[7.3.0]dodecene or 2,9-dioxabicyclo[6.3.0]undecene skeleton from

An asymmetric total synthesis and structure confirmation of (+)-(3E)-isolaurefucin methyl ether (2a) was accomplished. Our synthesis features two complementary routes to construct the α,α’-trans-2,8- dioxabicyclo[5.2.1]decane skeleton of the natu

Substrate-controlled asymmetric total syntheses of (+)-microcladallenes A, B, and C have been accomplished based on the proposed structures. The syntheses of microcladallenes A and B confirmed the structures and absolute configurations of both natura
