ASYMMETRIC-SYNTHESIS OF 2-ARYL-TETRAHYDROPYRANS VIA ARENE CHROMIUM TRICARBONYL METHODOLOGY .1. CIS-2-ARYL-4-CHLORO-TETRAHYDROPYRANS
Treatment of acetals derived from ortho substituted benzaldehyde chromium tricarbonyl complexes and methanol with homoallylic alcohol and titanium tetrachloride produces the corresponding (RS,RS,SR,RS)-cis-2-aryl-4-chloro-tetrahydropyran complexes completely diastereoselectively.
