ChemInform Abstract: SYNTHESIS OF DIHYDROBENZOFURANS FROM PHENOLIC MANNICH BASES AND THEIR QUATERNIZED DERIVATIVES

Stereoselective Partial Synthesis of (+)‐Pisiferic Acid

“…During the nucleophilic cleavage of the C(6)-0 bond, methanethiol was eliminated [29] Dehydroahietic Acid (2). Acid 2 a i d its ester 3 were obtained from Sacotan 9OCw as described in [37] [38], and 4-6 as described in [39][40][41][42][43].…”
