A wide range of substrates with various olefin geometries and size of the R and R1 groups were tested and all gave high diastereoselectivity. PMB- and TBS-protected remote alcohols were compatible for these reaction conditions. The use of chiral starting material (as shown in the second paper) yielded good selectivity, making this a valuable synthetic tool for synthesis of these furans.
