The transition metal-catalyzed allylic etherification represents a fundamentally important cross-coupling reaction for the construction of allylic ethers. We have developed a new regio- and enantiospecific rhodium-catalyzed allylic etherification of acycl

A convergent enantioselective synthesis of penicimarin B, aspergillumarin A and B has been reported using Brown's allylation, DeBrabander-Bhattacharjee lactonization and Grubbs cross coupling metathesis. During this synthesis we have standardized the conditions for DeBrabande-Bhattacharjee lactonization to obtain excellent yield (>90%).

A simple and efficient stereoselective synthesis of macrolactone, (+)-cephalosporolide D has been accomplished in 13 steps from inexpensive and commercially available starting materials in an overall yield of 17%, respectively. This convergent synthesis u
Iridium-catalyzed intermolecular allylic etherification with aliphatic alkoxides: Asymmetric synthesis of dihydropyrans and dihydrofurans

Hindered chiral ethers with one or two stereocenters are now readily available by allylic etherification of primary and secondary alkoxides (see reaction). When an Ir-phosphoramidite complex is used as the catalyst, the reaction proceeds with high regio-, enantio-, and diastereoselectivity. Np = 1-naphthyl.
